Cardiovascular Disease Research and Resources — The

Cardiovascular disease (CVD) is a leading cause of death both worldwide and in the United States, with mortality rates increasing worldwide. 4 In 2021, CVD was responsible for more than 17 million deaths globally. Although it is traditionally understood as a disease arising from diet, obesity, poor physical fitness and family history, research is finding effects from the environment—from air

Toxic chemicals can be stored into tissues of species, especially fat tissues. Bioaccumulation of cadmium in animals is high compared to most of the other metals, as it is assimilated rapidly and excreted slowly. Also the sensitivity of individuals of a particular species to a pollutant may be influenced by factors such as , age, or size.
