Accumulation of heavy metals in fish is considered a critical problem for human health. Therefore, the study aimed to quantify the concentrations of iron (Fe), zinc (Zn), manganese (Mn), and lead (Pb) in Oreochromis niloticus and Clarias gariepinus from two areas in Al Sharqia governorate, Egypt, from September 2017 to August 2018. A human health risk assessment was conducted to evaluate the potential hazards associated with fish consumption. Metals concentrations (mg/kg dry weight) in muscles of catfish ranged 1.88-221.26 for Fe; 1.78-19.77 for Zn; BDL-238.51 for Mn; BDL-22.75 for Pb. In muscles of tilapia fish metals concentrations ranged 7.96-149.10 for Fe; 1.20-19.77 for Zn; BDL-230.82 for Mn; BDL-25.93 for Pb. Pb had Hazard quotients (HQs) which indicated potential health risks to tilapia consumers at both study areas and catfish consumers at the Faqous area. Fishermen were at higher risk compared to the other consumers.

An investigation into the vitamins composition levels in Clariasgariepinus fish was carried out and reported in dry extract/fresh; dry extract / smoked-dried on individual vitamins and the sum of the whole vitamins. Parts investigated were liver, muscle and head. Whereas fresh and smoked-dried data were laboratory results, the dry extract portions were calculated and reported as dry extract /fresh sample, dry extract / smoked-dried sample for liver, muscle and head. Results obtained ran thus and all values were in mg/100g vitamin where d = difference, CV% = coefficient of variation and % difference = % value that shows what made dry extract value greater than its reported comparison: dry extract/fresh, % d = 74.5 (all), CV% = 84.0 (all), in liver; dry extract/smoked, % d =24.5 (all), CV% = 19.7 (all), in liver; dry extract/fresh, % d = 74.3 (all), CV% = 83.6 (all), in muscle; ndry extract/smoked, % d = 10.2 (all), CV% =7.60 (all), in muscle;m dry extract/fresh, % d = 68.5 (all), CV% = 73.7 (all), in head; dry extract/smoked, % d = 9.10 (all), CV% = 6.74 (all), in head; dry extract/fresh, % d = 71.9- 74.5, CV% = 79.4 - 82.4 in total vitamin body load; dry extract/smoked, % d = 9. 69- 24.5, CV% = 7.20 - 19.7 in total vitamin body load; dry extract (fresh) – dry extract (smoked), %d = 69.6 - 82.0 in liver; dry extract (fresh) – dry extract (smoked), %d = 72.3 - 76.3 in muscle; dry extract (fresh) – dry extract (smoked), %d = 62.9 - 75.2 in head; dry extract (fresh) – dry extract (smoked), %d = 69.7- 79.0 in total vitamins body load.Among the dry extract values calculated from fresh samples and subjected to chi-square (χ2) values, significant values were observed in vitamins B6, C, A, B1, D, E and total at α=0.05. In the dry extract values from smoked samples, only three significant χ2 values in vitamins A, E and total were observed. In reflection to vitamin concentration levels, percentage higher levels in dry extracts (from fresh) had these trends: liver (74.5%) > muscle (74.3%) > head (68.5%) whereas from smoked, we had liver (24.5%) > muscle (10.2%) > head (9.10%). Also total vitamin body load from dry extract (fresh) was 71.9-74.5% difference and dry extract (smoked) was 9.69 -24.5% difference. It should be noted that liver occupied the higher part of the range in the two comparisons, like 74.5% (fresh) and 24.5% (smoked).

This study was initiated in order to study cultural practices and assess levels of contamination in pesticide residues of onion samples produced in the region of Boucle du Mouhoun, Burkina Faso. A collection of samples was carried out at three gardening sites. A survey was also carried out to list the various pesticides used on market gardening sites and the practices for using pesticides. The QuEChERS method allowed the quantification of pesticides. The results show that 93% of the market gardeners were men, and more than 67% were between 25 and 35 years old. Nearly 55% of market gardeners are illiterate and do not have adequate means of protection when applying pesticides. A total of 16 pesticides have been accounted and most of them are Category II which are dangerous for human health and environment. 12 pesticide residues were quantified. Most of the active substances detected above the MRL (set by Codex Alimentarius and EU) were from the organochlorine family. These results reveal a fairly high level of contamination for pesticide residues. The study revealed that cultivation practices in market gardening sites as well as the consumption of onion pose numerous health risks for humans and the environment.

Aim: This study evaluated PAH content and health risks associated with consuming Clarais gariepinus (cat fish) from Ekulu Rivers, in Enugu, Nigeria fed with roofing sheet company effluent. Place and Duration of Study Design: Ekulu River, the largest body of water in the city of Enugu in Enugu State, south-eastern Nigeria, is a 25-kilometer long river (16mi) and it originates in the same city as well. The city is located on latitude 06o 21o N and 06o 30o and longitude 07o 26o E and 07o 37 Eo. Methodology: This analysis was conducted with the use of Gas Chromatography – Mass Spectroscopy (GC-MS) machine equipped with Flame ionization detector (FID). The health risks were evaluated by the mathematical models stipulated by USEPA and WHO. Results: The PAHs identified from the Clarias gariepinus samples were Acenaphthene, Acenaphthylene, Naphthalene, Fluorene, Phenanthrene, Anthracene, Flouranthene, Pyrene, Benzo(α)pyrene and Benzo (g-h-i)perylene. Benzo(α)pyrene and Benzo (g-h-i)perylene were predominant. The quantity of PAHs detected in all fish samples including the control ranged from below detectable limit (BDL) through 0.001 to 0.0786mg/kg. The LMW PAHs detected were 60 % while the HMW PAHs were 40 % of the total PAHs in isolated. The total PAH concentration observed from the different point locations were 0.1003 mg/kg, 0.0977 mg/kg, 0.1102 mg/kg and 0.0414 mg/kg for the downstream, upstream, POD and control respectively. The HQ and HI obtained in all point locations were < 1. The ILCR of all the PAHs detected were in the range of 10-5 to 10-9.  The benzo (α) pyrene in cat fish obtained from the POD has the most carcinogenic potency and also recorded the maximum limit (5E -03 mg/kg). Conclusion: it is pertinent to enlighten the fish consumers and mongers on the dangers posed by the consumption of fish from Ekulu River and also caution industries with injudicious effluent disposal into water bodies.

Appreciable levels of trace metals have been reported in the Tano basin, but data on the corresponding levels in fish and the risk they pose to consumers are limited. The levels of 7 trace metals in 18 fish muscles were assessed between November 2016 and October 2017 using acid digestion and PerkinElmer (PinAACle 900T) Atomic Absorption Spectrophotometry. Apart from Cu, all the metals studied were detected in all fish samples. The levels of Cr, As, and Hg were higher than the acceptable levels of fish muscles. Cr concentration ranged from 16.10 ± 0.2 mg/kg in Clarias gariepinus to 57.9 ± 4.2 mg/kg in Sarotherodon galilaeus. The levels of As ranged from 1.01 ± 0.08 in Clarias gariepinus to 3.00 ± 0.01 mg/kg in Mormyrus rume. Hg level was 0.58 ± 0.69 mg/kg in Oreochromis niloticus and 2.52 ± 0.70 mg/kg in Ctenopoma kingsleyae. However, Pb, Zn, and Cd concentrations were below the Food and Agriculture Organization limits with low target hazard quotients in all fish samples, suggesting no possible noncarcinogenic risks to adult consumers. Possible noncarcinogenic and carcinogenic health risks were recorded for As, Hg, and Cr in all fish species. Strong associations were observed between Hg, As, Zn, and Cr and between Pb and Cd suggesting a possible common source. Mormyrus rume fish species was under stress in the river, but the remaining species were in good condition. Periodic monitoring of trace metal concentrations in fish and enforcement of the buffer zone policy are recommended.

Abstract The mussel M. galloprovincialis is one of the most popular species in world’s mariculture and environment pollution bioindicators. Although this mollusk was in a focus of numerous publications, the detoxifying and accumulating role of some of its body parts was insufficiently studied. In the present work, using inductively coupled plasma mass spectrometry, the distribution of Cr, Co, Ni, Cu, Zn, As, Cd, Hg, Pb in soft tissues, byssus, and shell liquor of this bivalve was studied for the first time as a function of sampling location in the Black Sea off southwestern Crimea. Multivariate analysis showed significant differences in the overall distribution of the elements among the body parts and sampling sites under consideration. Human health risks from the consumption of this mollusk were shown to be unlikely. Byssus of M. galloprovincialis was characterized as an ideal indicator of marine environment pollution with Ni, Cu, Pb, Сo, and Cr as it contained the highest contents of these elements among the body parts under study (Ni up to 91%, Cu and Pb up to 79%). For the first time, the concentrations of trace elements were determined in the shell liquor and its role as the trace element excretion system was demonstrated. In the shell liquor, the largest share among the body parts was that of Hg (up to 71%). In soft tissues, Zn, Cd and As were in largest proportions among the body parts (63, 62, and 54%, respectively). The trace element contents in soft tissues of M. galloprovincialis decreased in the following order: Zn > Cu > As > Ni > Pb > Cd > Cr > Co > Hg.

Background. Aquatic pollution by heavy metals has become a global problem and is of great concern due to the detrimental effects on aquatic ecosystems and possible human uptake. Objectives. The present study aimed to evaluate tissue bioaccumulations of heavy metals and possible human health risks in addition to associated cellular damages in fish for sale in a fish market in Abuja, Nigeria. Methods. Clarias gariepinus sold at the Kado Fish Market in Abuja, Nigeria, in March–April 2017 and March–April 2018 were randomly purchased and sampled. The heavy metal contents of the sampled fish were assayed and used to assess the extent of potential health risks to human consumers. The extent of histopathological changes associated with the bioaccumulations in the sampled fish were also evaluated according to standard procedures. Results. Levels of most heavy metals were above permissible limits, except for lower levels of zinc (Zn) in liver and muscle and higher levels of lead (Pb) in muscle in the sampled fish. Similarly, significant (p&lt;0.05) liver bioaccumulation occurred for Zinc (Zn), chromium (Cr), iron (Fe), and copper (Cu) compared to their levels in muscle. The total hazard index (non-cancer risk across all metals) was 0.0415, which is very low and acceptable. The cancer risks ranged between the acceptable values of 1.98 × 10−5 – 3.71 × 10−6. Associated histopathological changes, which occurred in the sampled fish, differed between the various assayed tissues. Conclusions. Most of the heavy metals were significantly bioaccumulated (p&lt;0.05) and were above the permissible levels, particularly in liver samples. The levels of muscle heavy metal bioaccumulation in the sampled fish posed no apparent cancer or non-cancer health risks to human consumers. However, further efforts are needed to minimize heavy metal aquatic environmental pollution to safeguard the health of aquatic flora and fauna and human consumers because of the tendency of these pollutants to persist and bioaccumulate to toxic levels over time.
