The state of Massachusetts enacted the Toxic Use Reduction Act (TURA) in 1989. Ongoing research should be carried out to detect the spread of contamination resulting in any toxic threats to human health and environment in the future. In the case of the most contaminated samples, materials should be excavated and removed. On some hot-spots with metallurgical industry, improved assessments for better environmental practices are recommended. The severity of the risks identified on the hot-spot areas depends on the particular use of the local site. More research should be done in order to determine these toxic threats at the studied sites. A potential adverse health effects exist in this case. Moreover some of samples polluted with arsenic and cadmium showed exceeded hazard quotient (HQ). Several samples polluted with arsenic showed that adverse carcinogenic effects may occur in the long term. The most risky heavy metal on the hot-spot areas was arsenic followed by cadmium.

Concentration of heavy metals exceed not only levels of sediment quality criteria for protection of benthic animals drafted for Thailand but in some cases also levels of pollution limits for industrial or general use based on US EPA.Īnalysis using the Risk-Integrated Software for Cleanups (RISC) indicated the following results. The high levels of heavy metals were observed in sediments and soils in all the hot-spot areas (especially arsenic and cadmium). These levels of pollutants represent significant threats to environment and human health. There are several spots where hazardous levels of arsenic, mercury, lead, and cadmium were found in soils and sediments.

A series of samples were taken at contaminated sites and compared with the legal pollution criteria.
Users will also need to make use of their existing TV service provider to enjoy the media player.This study focused on monitoring and evaluation of concentrations of heavy metals in sediments, soils, and ashes at eight industrial hot-spot areas in Thailand. That said, the IPTV itself does not actually create any visual or audio content, provide any subscriptions, or sell any streams. It effectively acts as a medium to grow IPTV businesses.
