“…The maximum Pb concentration of 4.943 mg/kg was found in brain samples collected from the Madhya Badda Kacha Bazar area, and the lowest value was obtained from liver samples collected from the Mohammadpur area of DNCC. The concentration of lead in chicken muscle samples was higher compared to the studies done by [17,[35][36][37][38] and lower compared to that of [15,[39][40][41]. Other investigators recorded the same results (0.49 mg kg-1) from liver samples [12].…”

Food safety and security have now been regarded as a significant emerging area within the food supply chain leading to scientific and public health concerns in the global world. The poultry sector is a substantial threat to heavy metal intoxication for Bangladeshi people due to contaminated drinking water and feed sources, as well as the poultry sector’s surrounding environment and soil. This study was carried out to ascertain the residual concentrations of heavy metals (Pb, Cd) and trace elements (Cr, Fe, Cu, and Zn) in various edible chicken body parts (breast, liver, gizzard, heart, kidney, and brain) to observe the quality of the consumed chickens and to assess public health risk. Atomic absorption spectrometry (AAS) was used to check the content of toxic heavy metals and trace elements in 108 samples of 18 broiler chickens collected from six different locations of Dhaka North City Corporation markets in Bangladesh. The measured concentrations (mg/kg fresh weight) ranged from 0.33±0.2 to 4.6±0.4, 0.004±0.0 to 0.125±0.2, 0.006±0.0 to 0.94±0.4, 4.05±4.2 to 92.31±48.8, 0.67±0.006 to 4.15±2.7, and 4.45±0.62 to 23.75±4.3, for Pb, Cd, Cr, Fe, Cu, and Zn respectively. Except for Pb and Cu most of the investigated heavy metals and trace element levels in chickens were lower than the maximum allowable concentration (MAC) set by FAO/WHO and other regulatory agencies., The estimated level of Pb was nearly six times higher in the chicken brain. The estimated daily intake (EDI) values for all the studied metals were below the preliminary tolerated daily intake (PTDI). The target hazard quotient (THQ) values of the broiler chicken meat samples varied for adults and children, and the range was found to be 0.037–0.073 for Pb, 0.007–0.01 for Cd, 0.0–0.08 for Cr, 0.002–0.004 for Fe, for 0.00–0.002 Cu, and 0.004–0.008 for Zn, not exceeding the maximum level of 1 according to USEPA. The calculated THQ and total target hazard quotient (TTHQ) values were measured at less than one, suggesting that the consumption of chicken meat has no carcinogenic danger to its consumers. The Target carcinogenic risks (TCRs) of Pb, Cd, Cr, and Cu were within acceptable limits. The TCR values for children were, to some extent, higher than that of adults, which proposes that regular monitoring of both harmful and essential elements in chicken samples is necessary to determine whether or not any possible health risk to consumers exists. In terms of health, this study demonstrated that consumers are chronically exposed to elemental contamination with carcinogenic and non-carcinogenic effects.

“…The food chain and poultry origin food products are most likely to be contaminated by the effluent discharges caused by rapid urbanization, fast industrialization, the use of inorganic fertilizers in crop fields, unplanned lead acid rechargeable batteries recycling, emissions of transport and dumping waste from municipal and industrial areas, contamination of water bodies, etc. [ 29 ], which can be detrimental to both the environment and public health. Industrial wastes discharged from textile and tannery factories contain hazardous heavy metals above the normal levels.…”

“…In addition, these contaminants bioaccumulate in the human and animal body, leading to serious consequences [ 30 , 31 ]. Heavy metals such as arsenic, chromium and lead in broiler meat might exhibit toxicity and a carcinogenic effect even at low concentration following a regular consumption of contaminated poultry products [ 29 ]. These heavy metals are also recognized as human carcinogenic agents by the International Agency for Research on Cancer and the United States Environmental Protection Agency [ 5 ].…”

Assessment of Heavy Metals Contamination and Antimicrobial Drugs Residue in Broiler Edible Tissues in Bangladesh

There are substantial public health consequences when hazardous heavy metal contaminants and antimicrobial drug residues are present in broiler edible tissues. This study aimed to assess the concentration of antimicrobial drugs and heavy metals residues in broiler meat, bones and edible composites (combinations of liver, kidney and gizzard). Samples were collected from different types of broiler farms, broiler wet meat markets and supermarkets, covering all five divisions of Bangladesh. The antimicrobial drug and heavy metal residues were analyzed by uHPLC and ICP-MS, respectively. In addition, a cross-sectional survey was conducted among broiler meat consumers in the study areas to evaluate their attitude towards the consumption of broiler meat. The survey clearly stated that broiler meat consumers in Bangladesh have a negative attitude toward the consumption of broiler meat, although all respondents reported to eat broiler meat regularly. The antibiotic with the highest prevalence of residues in broiler edible tissues was oxytetracycline, followed by doxycycline, sulphadiazine and chloramphenicol. On the other hand, all collected broiler edible tissues contained chromium and lead, followed by arsenic. The fact of the matter is that the antimicrobial drugs and heavy metals residues were found to be below the maximum residue limit (MRL), except for the lead content. In addition, the broiler meat samples from supermarkets had lower levels of antimicrobial drugs and heavy metals residue compared to the broiler meat collected from various types of farms and broiler wet meat markets. Irrespective of the source, broiler meat was found to contain antimicrobial drugs and heavy metals residues below the MRL, except for lead, suggesting that broiler meat is safe for human consumption. Therefore, raising public awareness regarding misconceptions about broiler meat consumption among consumers would be warranted.

“…Another recent study that involved the assessment of heavy and toxic metal concentrations of lead, cadmium, arsenic and mercury in broiler chicken conducted in four major cities of Tamil Nadu, revealed that lead concentrations in breast (MRL 0.1mg/kg) and liver (MRL 0.5mg/kg) samples exceeded the maximum residue level in all cities [13]. Similarly, arsenic was found to be in excess of excess of MRL of 0.1mg/kg in the chicken breast samples in all cities.…”

Heavy Metals and their OmnipresenceHeavy metals are naturally occurring on the earth's crust [1] which have eventually found their way into soil, air and water bodies due to erosion over the years. Heavy metals are usually defined on the basis of atomic number, atomic mass or density. When the atomic number of any metal is above 20, or the atomic mass is above 23 or the density is above 5g cm ` it is characterized as heavy metals. Out of the 118 elements that have been identified as earth's essential building blocks by scientists, there are around 99 elements that could be called heavy metals according to the above criteria. Some examples of heavy metals according to this parameter are gold, silver, platinum, copper, selenium, zinc, cobalt, iron, tin, lead, tungsten, gold, iridium, rhodium, and platinum. But beyond a certain concentration all elements, be it heavy or light may be toxic. But when an element is not harmful in smaller concentrations, we do not consider it toxic. What is interesting is that not even all heavy metals are toxic in nature at small concentrations. In fact, some of them are considered essential for various bodily functions, like selenium which works like an antioxidant and some heavy metals like gold, which are non-corrosive and non-reactive in nature are called "noble metals". Noble metals like gold, silver, platinum are not considered toxic heavy metals even though they fulfil the criteria of atomic number, atomic mass and density as mentioned above.There are many other heavy metals with positive effects on the human body. Like, copper aids in the transports of electrons and oxygen, cobalt aids in cellular metabolism [1] etc. But on the other hand, certain heavy metals that represent the "dark side of chemistry" are those that Crimson PublishersWings to the Research
