Salmon and Orca Survival Threatened by Chlorpyrifos Pesticide: Government Report
A group of three widely used agricultural pesticides jeopardizes the survival of endangered salmon, according to a National Marine Fisheries Service (NMFS) biological opinion unveiled this week. Chlorpyrifos, malathion and diazinon—all organophosphate pesticides—harm salmon and their habitat to the point that their survival and recovery are at risk, according to the report. Southern Resident Killer Whales, or orcas, are also at risk as they depend on salmon.
The NMFS crafted the report to comply with a 2014 court deadline for the agency to determine whether these pesticides threatened salmon with extinction. Upon determining that these organophosphates jeopardize salmon survival, the biological opinion offers three options for protective measures to avoid that outcome with a variety of measures including buffer zones, spray reduction technologies and pesticide stewardship programs.
"The best available science clearly shows these pesticides are a major threat to endangered salmon and to our orca whales, which need salmon to survive," said Patti Goldman, managing attorney at Earthjustice. "These pesticides are bad for people every way they are exposed to it and toxic to salmon."
Chlorpyrifos, widely used in citrus, nuts and orchards, is acutely toxic and associated with neurodevelopmental harms in children. The U.S. Environmental Protection Agency (EPA) refused to ban chlorpyrifos in 2017, despite overwhelming evidence that shows the pesticide harms children, workers and the environment.
Malathion is used in more than 100 food crops, and about half of total applications in the U.S. are on alfalfa, cotton, rice and wheat. A number of growth anomalies have been observed when fish were exposed to malathion, according to studies. Diazinon is used on rice, fruit trees, sugarcane, corn, potatoes and horticultural plants.
NMFS had a Dec. 31, 2017, deadline for completing the consultations for these three pesticides, and was on track to meet this milestone and issue a biological opinion. Dow AgroSciences asked the agencies last April to derail the consultation process. Late last year, the Trump administration asked the courts to give agencies a two-year delay but complied with the 2017 deadline after Earthjustice and the fishermen and conservation groups it represents pushed back.
"Salmon have been waiting four decades for relief from toxic pesticides in many of our rivers," said Glen Spain, Northwest regional director of the Pacific Coast Federation of Fishermen's Associations. "The agencies should do their job."
This case is one in a series of cases that have pushed to ensure that endangered salmon on the West Coast are safe from toxic pesticides, as required by the Endangered Species Act. In 2002, a successful lawsuit brought by Earthjustice established that the Environmental Protection Agency has the duty to protect salmon and comply with the Endangered Species Act when registering pesticides for use.
At that time, the U.S. District Court in Seattle found that the federal government had failed to protect 26 endangered and threatened species of salmon and steelhead from 54 toxic pesticides. The judge ordered EPA to consult with NMFS to identify permanent measures needed to protect the salmon and steelhead from the pesticides.
Since then and as a result of multiple lawsuits, the EPA started the process of consulting with NMFS to determine whether EPA's pesticide registrations impacts endangered salmon and steelhead. The Fisheries Service delayed doing its part, which led to this lawsuit and court-ordered deadlines.
Pesticides have profound effects on Northwest salmon and are a serious factor in their decline. Now that the biological opinion has been released, fishermen and conservation groups want the EPA to move expeditiously to put the protective measures in place.
"Those of us who fight to protect and restore rivers and their critical fisheries are very pleased that the biological opinions were released," said Sharon Selvaggio, of Northwest Center for Alternatives to Pesticides. "To protect salmon, we need to respond to what the science is showing us."
Federal government inaction puts at risk billions of dollars and thousands of jobs. As recently as the late 1980s, salmon and steelhead fishing in Oregon, Washington, Idaho and Northern California brought in $1.25 billion to the regional economy and supported more than 62,000 family wage jobs, according to independent economic studies. Government studies from Washington, Oregon and California show the economic benefits of dwindling salmon have grown exponentially since then.
Salmon runs have declined because of dams, climate change, widespread habitat loss and pesticide runoff. Scientists have found that, even at low levels, pesticides can cause the abnormal sexual development of salmon and impair their swimming ability, growth, development, behavior and reproduction.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>
