Arsenic Contamination

Decent Essays
Arsenic is an invisible killer that many people may be drinking as I write this article. It was such a problem for the United States, that in 2001, the US Environmental Protection Agency had to lower the maximum level of arsenic allowed in drinking water from 50 micrograms per liter (ug/L) to 10 micrograms per liter (ug/Liter) (Ryker, 2001). Despite this change in policy, this issue of arsenic contamination continues, and is even more widespread in many more places outside of the United States. Unlike the U.S., underdeveloped countries like India, Cambodia, and Bangladesh cannot rely on the usual testing’s more developed countries are accustomed to. For example, a study in Bangladesh (2009) showed 13% (1,883) of their findings (14,492 samples) had an arsenic concentration that exceeded 50 ug/Liters (Rodrigues et al, 2016). The old maximum stated by EPA back in 2001. Information like this is then used, in hopes that it creates more of an importance…show more content…
For this cohort, the study uses 524 children ranging in ages from 1, 12, and 20-40 months (Rodrigues et al, 2016). Their study examines the blood lead, arsenic, and manganese, but for our purposes we will focus on arsenic concentration. The study stated that the increased water arsenic levels were associated with a decrease in cognitive scores based on the above average arsenic concentration (Rodrigues et al, 2016). These women and children were recruited from areas the scientists knew the water was contaminated with arsenic. The areas included, Sirajdikhan and Pabna regions between the years 2008 and 2011. Tests to examine their cognitive level ranged from language function, motor skills, verbal abilities, and long-term memory. These tests showed that there was a relation between arsenic and lower neurodevelopment, with Pabna having higher levels than Sirajdikhan (Rodrigues et al,
