2020-4-1Significant effects on reproduction are also attributed to mercury and methylmercury poses a particular risk to the developing fetus since it readily crosses the placental barrier and can damage the developing nervous system. In birds adverse effects of mercury on reproduction can occur at egg concentrations as low as 0.05 to 2.0 mgkg wet
2014-6-21CHAPTER 7. THE GREENHOUSE EFFECT . We examine in this chapter the role played by atmospheric gases in controlling the temperature of the Earth. The main source of heat to the Earth is solar energy which is transmitted from the Sun to the Earth
Mercury is a toxic heavy metal which is widely dispersed in nature. Most human exposure results from fish consumption or dental amalgam. Mercury occurs in several chemical forms with complex pharmacokinetics. Mercury is capable of inducing a wide range of clinical presentations. Diagnosis of mercury toxicity can be challenging but can be obtained with reasonable reliability
