Lab 2 For my conclusion I will write about the differences between people drowning in freshwater compared to people drowning in saltwater. When someone drowns it means that their lungs (respiratory system) has been blocked from receiving oxygen by a liquid. Majority of the time it is water that people drown in. “Drowning is the third most common cause of accidental death worldwide‚ accounting for 7% of all injury related deaths” (MedicineNet). Water is the most common way that people drown‚ but

Hem (1989) stated that major part of fluorine present in groundwater sources‚ since it is stored in rock minerals‚ unlike chlorine that is mostly present in seawater. Thus‚ it leads us to a conclusion that significant part of fluorine intake

Thus differentiating brittle from ductile rocks has been the key to unique success in shale gas reservoirs. In the lab scale‚ The Brittle failure is occurred when the ability of the rock to resist load decreases with increasing deformation. Brittle failure is induced with materials that undergo little to no permanent deformation before failure and depending on the test

ARSENIC IN DRINKING WATER Arsenic in Drinking Water: Effect on Health ABSTRACT: Drinking water can be contaminated with arsenic through natural resources such as soils and rocks‚ but it also results from human activities. Long-term ingestion of arsenic exposure through drinking water can cause multiple adverse health effects including cardiovascular‚ pulmonary‚ immunological‚ neurological effects and endocrine problems such as diabetes. Ingestion of arsenic-rich water can increase the risk
