“…In contrast, cadmium was below the detectable level in all samples, which is consistent with reports from Malaysia (Baharom & Ishak, 2015 ; Ismail & Saleh, 2012 ) and Ghana (Gbogbo et al , 2018 ). Yet, previous studies from Iraq have detected low levels of cadmium in different locales (Al –Jubouri and Salman, 2019 ; Mensoor and Said, 2018 ). Moreover, a significantly high level was reported from Sulaimani city (Rashed, 2012 ).…”

Food contamination with heavy metals may pose a serious threat to human health. Fishes are the most common seafood globally. This study aimed to evaluate the levels of heavy metals in different fishes sold in Erbil city markets. The targeted heavy metal elements were cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), mercury (Hg), manganese (Mn), nickel (Ni), selenium (Se), and zinc (Zn). Seventeen dorsal meat samples were digested and subjected to metal analysis by Inductively Coupled Plasma Optical Emission Spectrometry. Co, Mn, Cu and Se were detected in all samples, while cadmium was below the detectable level in all samples. The average concentrations of targeted trace elements were 0.03±0.016, 0.02±0.03, 0.07±0.08, 0.10±0.08, 0.03±0.03, and 2.90±3.33 mg/kg for cobalt, chromium, copper, manganese, nickel, and zinc, respectively. Lead was only found in one sample (5.88%). On the contrary, mercury was detected in all samples but in low concentration (0.14±0.07). All detected heavy metals with specified permissible limits by FAO/WHO were significantly lower than the permissible limits. Based on detected levels of targeted heavy metals, consumption of such fish has no potential risks to human.

“…Consequently, Tigris River water would be heavily polluted and contaminated with biomedical and chemical substances. This is a very serious environmental and public health problem that was being previously raised and reported by several studies [23][24][25]. The remaining seven hospitals had incinerators but the incineration process was ineffective as the incineration temperature was not enough for complete incineration in all the surveyed hospitals.…”

There is a lack of information about medical waste management in Iraq. This study aims to monitor and evaluate the current situation of medical waste management in Baghdad as it represents the capital and the biggest populated city in Iraq. About 32% of hospitals are located in Baghdad. Ten state-owned hospitals in Baghdad with the biggest bed capacity were investigated. The study used structured interviews with staff in charge of waste management in the sampled hospitals to collect data. The results showed that the generation rate of medical waste in the ten hospitals was 0.5 kg/(bed•day). The study also found that there were insufficient, ineffective, and improper isolation, collection, storing, processing, and safe disposal of medical wastes in the sampled public hospitals of Baghdad. The study recommended that the Iraqi Ministry of Health takes extensive and quick effective measures to better monitor and evaluate medical waste management and provide ongoing training to personnel responsible for waste management in the hospitals.

“…Both metals (Fe and Cr) are transferred from soil to Tigris stream via erosion and weathering 26 . Mansoor and Said (2018) 27 indicated to the relatively high concentration of VI chromium in the liver, gill, and muscles of the freshwater fish, genus Barbus found in Tigris river in Baghdad-Iraq. Al-Taee (2004) 28 referred to the high activity of Mn compounds in the acidic medium, and that abundance of carbonate and bicarbonate in Tigris stream middle and South Iraq are lessening Mn activity.…”

The purpose of the study is to pursue some heavy metals in the aqueous environment of Tigris river that passes through Mosul city prior to the bioaccumulation of such metals in catfish Silurus glanis and its intestinal tapeworm Postgangesia armata. Methods: Silurus glanis, a freshwater fish were hunted from Tigris river passing through Al-Rashidiya region/Nineveh Governorate, North Iraq, during November 2017 and May 2018. Bioaccumulation of Fe, Cr, and Mn were estimated in different body tissues of infected and uninfected catfish, and in catfish intestinal tapeworm P. armata. Atomic absorption Spectrophotometer was used to estimate heavy metal concentration as µg of a particular metal/gm of fresh weight. Results: Concentration of the metals in catfish tissues were in the order of Mn > Fe > Cr. Whereas, concentration of the metals of the tapeworm P. armata were in the order: Fe > Mn > Cr. Moreover, mean concentrations of the three heavy metals (Cr; Fe and Mn) were lesser in body tissues of infected catfish than in the uninfected fish. This lessening of metals accumulation in the infected fish may be related to the presence of the intestinal tapeworm. It also appeared that the three metals are mostly accumulated in liver of the catfish, then in gills, and muscles at lesser extent. Conclusions: Present work is drawn out that measuring concentration of heavy metals in parasitic and host tissues that inhabit a certain aqueous environment could be adopted as bioindicators for assessing heavy metals pollution.
