This study includes various aspects of environmental hazards which may be correlated to human beings directly or indirectly. Heavy metals are very persistent and widespread contaminants in the world. So our research clings to black kites as helpful bio-indicator in our learning. The industrial era and escalating automobiles have polluted environment in many ways, some of the toxic materials like lead are fed out throughout the public areas with high density population. There are certain resources such as mining, smelting, refining, manufacturing processes and by the use of lead containing products. Heavy metals may get absorbed in the bird’s tissues through various sources like nasal passage or by feeding contaminated food etc. There are a large number of pathways of their entry into the food web like air, water, soil, living organisms, and biogeochemical cycles. Our study elaborates that long and severe exposure of birds to heavy metals causes severe effects on growth, reproduction, development, behaviors, resistance to diseases and many other physiological mechanisms.

This manuscript evaluates the effect of vinegerized copper sulphate on morphology, gross pathology and histology of broiler chick organs such as on heart and gastrocnemius muscle. Findings include whether copper sulphate has beneficial or lethal effects on these organs, and to study the effects of copper sulphate on broilers to check the environmental pollution level. In practice vinegerized copper sulphate is added in the food of broilers which is used as a fungicide, algicide, as dietary supplement for poultry and a source of nutrition in animals and as a source of growth promotant. Copper effect all the body organs of the broiler chickens and also effect the growth. Copper is the most likely to become toxic when over supplemented. Copper toxicities can occur in cattle that consume excessive amounts of supplemented copper or feeds that have been contaminated with copper compounds used for other agricultural or industrial purposes. These heavy metal contents move into the human body when they eat the meat of the broilers and cause many hazardous effects. The waste of the broilers which is used in fertilizers is also the major cause of creating diseases in humans.

In this text the heavy metal (particularly lead) contamination in the Blue Rock Pigeons through their feathers or muscles and the effects of the lead contamination in the body are under scrutinized. Heavy metals are those metals which have certain toxic or poisonous effects in living bodies. A great concern all through the world is heavy metal contamination in living animals including birds. High concentrations of heavy metals play an important role in fluctuating and disturbing the nervous control of organism and rest of body systems. Birds have a significant role in the ecosystem. In this research pigeons are chosen as bio-indicator. The lead resources, transport mediums and contamination areas are discussed in my present study. The lead metal contamination in the living pigeons is through feathers and oral pathway, absorbed or intake material containing lead contamination leads to serious health related problems in the living organisms.
