The efficiency of lighting in producing these chemicals is unknown . " Gary Brown , Director of Iowa Woodbury County Emergency Response Services said , " The data and information generated by ASPECT provides first responders with a critical link that emergency responses do not currently have ; namely , real-time wide-area chemical detection information . The initial focus of the models in ChISELS is on low pressure chemical vapor deposition ( LPCVD ) , one of the processes employed in Sandia National Laboratories ' SUMMiT V technology , so the models employed are ballistic transport of chemical species from the reactor to and between surfaces and surface chemistry only ; all of which are designed to function in a massively parallel computational framework . In addition , the methodological approaches to be developed during the course of this research program should augment our ability to conduct scientifically-sound risk assessments for other chemicals and chemical mixtures of national concern . " Studies of people exposed to atrazine indicate that the chemical may be linked to a number of cancers , including prostate cancer and non-Hodgkin 's lymphoma . Since norepinephrine and dopamine are part of the same family of chemicals , called catecholamines , the findings suggest that whatever causes the loss of dopamine-producing nerve fibers in the brain also causes the loss of sympathetic nerve endings in other parts of the body . A second goal of the institute is to recruit graduate students and post-doctoral fellows to the chemical biology program . Some stripper products contain very strong chemicals . Relatively little use is made of machines , chemical fertilizer , or pesticides . " That is tens of thousands of acres of the American landscape that will not have chemicals like atrozine poured on them and pollution of the water and the cost to farm workers that comes from exposure to those chemicals .
