“…However, a study in Egypt indicated that relatively high mean value of Pb residues in muscles of sheep, and it was 1.884 ppm (FAO/WHO, 1992). The Pb content in the liver was relatively high but it fluctuated throughout the year and the highest concentration was estimated during summer (Vos et al, 1991). However, Pb concentration in the liver can reach up to 10 mg/kg in sheep reared in polluted areas.…”

“…(2) The means of the Pb concentration in the mutton, liver and kidney of local and Australian sheep were very high and represent over 5 times in comparison to that recorded in other countries like Holland and Egypt (Boulis, 1993;Vos et al, 1991) and (Attala, 1998). (3) Although the mutton of the Australian sheep has a higher significant mean Pb concentration than the local and Chinese sheep, the means of Pb concentration in the mutton of local, Australian and Chinese sheep marketed in Jordan were very high when compared to that recorded in other countries over 3 times on average.…”

“…The residues of Pb were detected in different slaughtered animals such as cattle, swine, poultry, horses, calves, and sheep (Salisbury et al, 1991). Furthermore, it was reported that the mean Pb concentration in meat, liver and kidney of sheep were 0.04, 0.85 and 0.36 mg/kg, respectively (Vos et al, 1991). In general, the safe permissible limit of Pb in meat and meat products was stipulated to be 1.0 mg/kg by Food and Agriculture Organization (FAO)/(WHO) World Health Organization (FAO/WHO, 1992); 0.5mg/kg by Egyptian standards (Egyptian, Organization for Standardization and Quality control, 1993); 0.5 mg/kg, by German guide ZEBB (EBBS, 1990); and 1.0 mg/kg by Codex Alimentarius Commission (FAO/WHO 2003).…”

A total of two hundred and forty random samples were collected equally from mutton, liver and kidney of 40 local (Jordanian) and 40 imported Australian sheep (40 each sub sample). Fresh samples were collected from 12-18 m old sheep slaughtered in abattoirs in Jordan in 2002. Besides, 40 fresh mutton samples of imported Chinese sheep were collected from different markets. Atomic absorption spectrometry (AAS) was used to estimate the lead (Pb) content of the samples. Results indicated that Australian mutton had significantly higher (p < 0.05) mean of lead pollution than that of the local and Chinese muttons. The mean concentration of lead (mg/kg) in Australian, local and Chinese muttons was 4.30, 3.15 and 2.17, respectively. The mean concentration of lead in Australian sheep liver was significantly higher (p < 0.05) than that recorded in the local sheep liver. The mean concentration of Pb in Australian and local sheep liver was 5.69 and 4.52 mg/kg, respectively. The mean concentrations of Pb in the kidney of the Australian and local sheep were not significantly different (p > 0.05). They were 4.59 and 3.87 mg/kg, respectively. On the basis of the samples lead level, 85, 92 and 87.5% of local, Australian and Chinese mutton respectively, exceeded the international safe permissible limit of 1.0 mg/kg. Furthermore, the effect of Pb on animal and human health was discussed.

“…The method described by Vos et al (1991) and GonzalezWeller et al (2006) was adopted in the extraction of metals from edible parts. The ashed samples of liver and muscle tissues were mixed with 3 ml of 3 N nitric acid and dried on a hot plate at 120 ± 15°C for half an hour, then placed in muffle furnace and temperature raised to 450°C for 1 h; this step was repeated three times to get constant weight, from which one gram samples were removed from muffle furnace, cooled to room temperature (28 ± 5°C) and dissolved in 1 ml of 1 N hydrochloric acid.…”

A study was carried out to determine the levels of heavy metals [(arsenic (As), mercury (Hg), cadmium (Cd) and lead (Pb)] contamination in soils and edible parts of free-range local chicken (liver, muscle tissues and abdominal fat) collected randomly in three locations viz Tabata, Kigogo and Vingunguti located in Dar es Salaam city, Tanzania. Concentration of Pb in soils ranged from 5.304 to 7.529, Cd from 0.046 to 0.055, Hg from 0.034 to 0.060 and As from 0.239 to 0.329 ppm, respectively. Lead concentration in soils differed significantly (P B 0.05) between locations. Differences in soil concentration of As, Hg and Cd between locations were not significant (P [ 0.05). Heavy metal concentration in chicken parts differed significantly between locations (P B 0.05). High lead concentration in chicken parts was registered in samples collected at Tabata than at Kigogo and Vingunguti. As and Cd concentration in soil and that in liver and Pb concentration in soil and that in muscle tissues were positive and significant correlated [(P B 0.001) and (P B 0.05)], respectively. Negative significant (P B 0.05) correlation was observed between Hg concentration in soils and that in liver and between As concentration in soils and Hg concentration in muscle tissues. Results have shown that heavy metals contaminated in soils may find route into different tissues and organs parts of free-range local chicken; a health concern, hence, calls for safe disposal of industrial and domestic potential sources of heavy metal contamination in soils.

“…Cadmium (Cd), lead (Pb), arsenic (As) and mercury (Hg) are nonessential biological metals that exhibit extreme toxicity, even at trace levels 11 . For instance, cadmium accumulation in the human body can induce skeletal damage, kidney dysfunction and reproductive deficiencies 12 , 13 ; Lead can significantly reduce semen quality, thus impairing human reproductive function 14 ; Arsenic can cause toxic and harmful biological effects such as liver, skin and bladder cancer 15 ; Mercury can cause adverse effects such as impair hearing, eyesight, and the nervous system 8 , 16 . The biological function of chromium is unclear, but when its concentration exceeds the threshold, it can cause damage to the liver, kidney, lungs and is recognized as a known carcinogen 9 , 17 .…”

Xincun Lagoon is an important fishing area in northern Hainan Island, China. It has long been exposed to pollutants from local sewage, breeding cages and fishing boats, resulting in serious pollution threats to the survival of fish. In this study, we examined the concentrations of seven trace metals (Cu, Pb, Zn, Cd, Hg, As and Cr) in sixteen economic fish species collected from Xincun Lagoon and their exposed environment (water and sediment). The concentrations of Pb and Zn in the water column were higher than the safety threshold stipulated by Chinese legislation, while the contents of all examined metals in the sediment and fish species were lower than the legislative thresholds set by China and international organizations. The contents of trace metals in the fish species in high trophic levels or those that prefer to live in/on the sediment layer were significantly higher than those in other trophic levels and pelagic/subbenthic fish, these species had homogeneous anthropogenic pollution sources for Cu, Zn, Cd, Hg and As. Our results show that the trace metal contents in fish were mainly affected by trophic level and habitat preference. The contribution of metal exposure from the sediment to metal accumulation in fish was lower than that in water, especially for the Cd and Hg in the sediment. These results provide valuable information for further understanding the species-specific patterns of metal accumulation in fish and the development of targeted conservation measures for the environment and fish consumers.
