A study on metal retention in U.S. public water systems (CWS) and other conditions, researchers at Columbia University Mailman School of Public Health found that increased levels of metals to CWSs serving semi-urban, independent Hispanic communities locally or nationally, it shows. about environmental welfare. These communities have the highest levels of uranium, selenium, barium, chromium, and arsenic concentrations.

Even at low levels, uranium is an important nutrient for the development of inflammatory diseases. To date, clinical research has been conducted on exposure to raw uranium despite the health effects of uranium emission from CWSs. Uranium in particular, is underappreciated in the literature as a drinking water contaminant of concern. The study results are published in a journal The Lancet Planetary Health.

“Previous studies have found links between chronic uranium depletion and high blood pressure, cardiovascular disease, breast cancer, and breast cancer. at high levels of knowledge, ”said Anne Nigra, Ph.D., assistant professor of Environmental Health Science at Columbia Mailman School of Public Health. “Our goals were to estimate the CWS metal fragments across the U.S., and to identify the sociodemographic subgroups served by these systems that exhibited high metal depletion values ​​or that exhibited high metal deficits. averages above the U.S. EPA’s maximum contaminant level (MCL). “

About 90 percent of Americans rely on public drinking water systems, with the vast majority of residents relying heavily on community water systems that serve the same population year -round. The researchers reviewed six -year EPA evaluation records for antimony, arsenic, barium, beryllium, cadmium, chromium, mercury, selenium, thallium, and uranium to determine if the levels were greater than high contaminant levels set by the EPA to regulate the levels for the six classes. of unclean things. This includes approximately 13 million records from 139,000 public water systems serving 290 million people each year. The researchers developed standard metal models for 37,915 CWS nationwide, and created a web -based map of the estimated metal values ​​at the CWS and county levels using possible evaluations. from.

Studies show that 2 · 1 percent of community water systems reported average uranium concentrations from 2000 to 2011 above the EPA’s higher contamination levels, and uranium was frequently detected during the inspection (63%). of time). Arsenic, barium, chromium, selenium, and uranium raised in CWSs serving semi-urban, Hispanic populations, raise concerns for these communities and the potential to reverse the similarities. Not to public drinking water.

Nigra and her colleagues note the correlation between the proliferation of CWS metal and semi-urban, Hispanic communities that report a lack of regulatory or conservation policies rather than world principle. The Hispanic / Latino population shows health differences in terms of increased mortality due to diabetes, as well as liver, kidney, and cardiovascular disease.

“Therefore, reform, implementation, and improvement policies are needed to reduce disparities in CWS metallurgy and to protect the communities served by public water systems and the High quality metal, ”Nigra said. “Such practices and policies effectively protect communities that are perceived to thrive on environmental governance and protect public health.
