“…In birds, metals are eliminated in the bile, through the kidneys (Burger and Gochfeld 1985), or in faeces (Rose and Parker 1983;Lebedeva 1997;Beyer et al 1998). However, it is not clear whether faecal levels of Ni are due to unabsorbed material or circulating metal that has been excreted through the bile.…”

“…Studies on the bioaccumulation and distribution of metals in avian tissues and organs were reviewed (Connors et al 1975;Custer and Mulhern 1983;Burger and Gochfeld 1985;Ohlendorf et al 1986;Falandysz and Szefer 1983;Falandysz 1983, 1987;Falandysz 1984Falandysz , 1986Honda et al 1985;Burger and Gochfeld 1985;Wiemeyer et al 1987;Kraus 1989;Ohlendorf et al 1991;Outridge and Scheuhammer 1993;Beyer et al 1998). In birds, metals accumulate in the liver and kidneys, although elevated levels of metals also have been found in feathers.…”

Nickel (Ni) is a naturally occurring element with many industrial uses, including in stainless steel, electroplating, pigments, and ceramics. Consequently, Ni may enter the environment from anthropogenic sources, resulting in locally elevated concentrations in soils. However, Ni is a minor essential element, and, therefore, biota have established systems that maintain Ni homeostasis. This paper discusses the role of Ni as an essential element and reviews storage, uptake, and transport systems used to maintain homeostasis within terrestrial biota. The bioaccumulation and distribution of metals in these organisms are also addressed. In all cases, information on Ni essentiality is very limited compared to other essential metals. However, the available data indicate that Ni behaves in a similar manner to other metals. Therefore, inferences specific to Ni may be made from an understanding of metal homeostasis in general. Nevertheless, it is evident that tissue and organ Ni concentrations and requirements vary considerably within and between species, and metal accumulation in various tissues within a single organism differs as well. High rates of Ni deposition around smelters indicate that Ni in acidic soils may reach concentrations that are toxic to plants and soil decomposers. However, with the exception of hyperaccumulator plants, Ni does not biomagnify in the terrestrial food web, suggesting that toxicity to higher trophic levels is unlikely.

“…One of the key ways for metals to enter the body of birds is through food, water, and by eating of sediment, lead shot and grit (non-food items). The direct consumption of soil contaminated with metals is a major cause of increased contamination in their bodies, even if the contaminant levels in plants or their prey has not increased (Beyer et al 1998).…”

The concentrations of four heavy metals zinc (Zn), lead (Pb), nickel (Ni) and cadmium (Cd) were determined in liver, kidney, muscle and brain of nine species of birds from the Chahmimeh Sistan from Iran, to assess metal levels and the potential risk to birds, and to the people who eat them. Higher levels of all metals were found in the brain of waterfowl than in the tissues of other birds (P < 0.05). There were no significant gender differences in heavy metals in all tissue. Levels of Pb, Cd, Ni and Zn in the liver and kidney varied as a function of feeding habitats; the median levels were higher in invertebrate predators than fish predators and omnivorous species (P < 0.05). Short distance migrating birds had higher median levels of heavy metals in liver and kidney than long distance migrant birds (P < 0.05). Ni levels in liver and kidney tissues in 56% of birds were higher than the critical thresholds levels for effects in birds. Our data indicate that environmental exposure to metals were higher in the wintering populations of birds in the Chahnimeh of Sistan from Iran. Concentration Zn, Pb and Cd in a small percentage of birds, and 56% nickel level in liver and 56% kidney concentrations in birds, were above toxicity levels. Examination EDI, EWI and HQ of the edible tissues (kidney, Liver and muscle) of these birds showed that their consumption is a threat to the health of the people of the region.

“…The process of bioaccumulation of heavy metals in birds is very complex and under the in uence of many factors, including climate, geographical conditions, physicochemical differences, and the mobility and bioavailability of metals (Aloupi et al 2017). Behavioral factors such as migration, foraging methods, grit collection, and position in the food chain influence exposure as well (Beyer et al 1998;Burger et al 2003;Peakall and Burger 2003). Metals are absorbed in the body, enter the blood circulation, and then exhibit different levels in living things or tissues in relation to reaction to lipids, solubility and transport in different speci c cells (Burger et al 2003).…”

Determining the exposure frequency and daily intake of birds, the Hazard Quotient for edible tissues (kidney, Liver and muscle) of these birds showed that their consumption provides a health risk to people consuming them.
