How did the author sample ticks at each of the study sites? The author dragged a piece of cloth along a transect every one to two weeks and collected ticks on the cloth. The author sprayed toxins on specified plots of vegetation, and collected all the dead ticks from the ground. The author used pitfall traps to capture ticks crawling along the ground. The author caught a variety of mammal and avian hosts and recovered ticks by dusting animals with a mild pesticide.   Article Link https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0201665

Environmental health and hazards

An organism's environment is the environment in which it lives and has an impact on its well-being. The World Health Organization (WHO) defines environmental health as "those aspects of public health, such as quality of life, that are influenced by physical, chemical, biological, social, and psychosocial components in the environment." Environmental health is concerned with both natural and man-made settings in order to enhance public health. Environmental science, occupational medicine, toxicology, and epidemiology are the key subdisciplines of environmental health.
