The United States Environmental Protection Agency (EPA) on Wednesday announced a plan to repeal a landmark pollution rule that aims to eliminate most greenhouse gas emissions from power plants in the next decade. Not only will power plants be able to release more greenhouse gases, but another regulatory rollback will allow them to pollute the […]
Congressional Republicans, along with the Trump administration, are trying to repeal Biden-era rules that require all lead pipes in the United States to be replaced, while lowering the lead limit in drinking water. Repeal of the revised public health standard has been a top priority of Republicans in Congress, according to a press release from […]
In a new study, scientists tested soil samples from residential and play areas in the Greater Fifth Ward, a neighborhood of Houston, Texas and found high concentrations of lead. The researchers tested for heavy metals and metalloids, such as lead, arsenic and mercury. While the levels for most of the heavy metals and metalloids appeared […]
To mark National Lead Poisoning Prevention Week — October 20 to 26 — the United States Environmental Protection Agency (EPA) has finalized stricter requirements for the identification and cleaning up of lead-based paint dust in homes and childcare facilities constructed before 1978. The new standards are the most recent action in the Biden-Harris administration’s strategy […]
A new study is warning that trace metals like lead, arsenic and mercury that are present in ocean water can become more toxic over time as factors like ocean warming and acidity can increase the bioavailability of these trace elements. Although these elements can naturally occur in coastal areas, their concentrations have increased due to […]
The United States has a legacy of lead contamination that could be affecting the environment around your home. A new study found that moss in older neighborhoods in Portland, Oregon, had lead levels that were much higher than in nearby rural areas due to lead-sheathed telecommunications cables and leaded gasoline. In pre-1960 Portland neighborhoods, the […]
A new study has found that approximately one in four households in the United States has soil lead levels exceeding the new U.S. Environmental Protection Agency (EPA)’s limit of 200 parts per million (ppm). The previous screening level was 400 ppm. For households that have multiple sources of lead exposure, the guidance level was lowered […]
A new study has found that lead exposure is more deadly than previous estimates, with about 5.5 million adults dying from cardiovascular disease linked to lead exposure in 2019 alone. People have long known that high exposures of lead are dangerous. And since the 1970s, we’ve known that even minimal lead exposure can be harmful, […]
Many cities in Canada and the U.S. used municipal incinerators to burn their waste and trash until the early 1970s, when most of the facilities were closed due to air pollution concerns. A new study by scientists at Duke University has found that the lead contamination produced by the incinerators could still be present in […]
