“…(Table 6). EDI; estimated daily intake, ADI; acceptable daily intake, HI; hazard index Previously, the residues of bifenthrin in okra samples from Pakistan were found to be signi cant and non-compliant with the standard MRLs, yet the health risk was found to be insigni cant which is consistent with the results of present study (Amjad et al, 2019). The results of another study from India reported possible health risk as hazard index ranging from 0.01 to 0.03 for bifenthrin, 0.10 to 0.12 for carbendazim and 0.03 for carbofuran (Ratnamma et al, 2020).…”

“…The residues of some organochlorine and organophosphate pesticides have been reported at high concentration in okra samples collected from Punjab, Pakistan using GC-ECD technique (Randhawa et al, 2016;Randhawa et al, 2015). The residues of pyrethroid pesticides in okra samples using GC-µECD from Punjab, Pakistan and their dietary risk have also been reported (Amjad et al, 2019). Pesticides residues in okra as a non-target crop grown close to a watermelon farm have also been reported from Ghana using GC/MS technique (Essumang et al, 2013).…”

European Union Reference Laboratory method for Fruits and Vegetable (EURL-FV-2010-M1) for the quanti cation of pesticide residues was veri ed for the determination of multiple pesticides residues in okra. The targeted pesticides were extracted using acetonitrile with citrate buffer salts followed by cleanup with primary secondary amine (PSA) and analyzed on LC-MS/MS. The recoveries for all the targeted pesticides were within an acceptable range of 70.1 -116.6% and precision in terms of RSD was 0.3 -18.1%, respectively. The limit of quanti cation ranged from 0.002 mg/kg for carbofuran to 0.5 mg/kg for αcypermethrin. The status of pesticide residues in okra (n= 21) available to consumers in the main markets of Pakistan has been determined by using this veri ed method. Sixty-two percent of the tested samples were contaminated out of which three samples were non-compliant with European Union Maximum residue limits (EU-MRL). The pesticides violating the EU-MRL were bifenthrin, thiamethoxam, and triazophos. For all the detected pesticides, estimated daily intake (EDI) ranged between 7.39×10 −6 and 1.78×10 −4 mg/kg of body weight while the values of Health Index (HI) uctuated between 8.9×10 −5 and 1.8×10 −2 .Although, residues of some pesticides were reported to be non-compliant with EU-MRLs, yet the risk posed by these pesticides to human health was insigni cant.

“…In another study of metal concentration from drilling waste discharges in Khyber Pakhtunkhwa, Ba, Zn, Ni, Mn, Cr, Cd, and Pb concentrations analysed by Atomic Regarding the concentration of these heavy metals, it was presented that the order of growth of such chemical elements was Pb>Cu>Fe>Cd>Ni and Zn [34,35]. The specific hazards associated with these metals (Pb, Ni, Fe, Zn, Cd, and Cu) in the environment are not the only pollution but also their persistence in nature and bioaccumulation through food chain [36]. A study was conducted in Kaduna state, Nigeria, on heavy metal content and physicochemical properties of soils from solid waste dumpsites and concentrations of 7 different heavy metals were in the range of 19.0-5741.0 mg/kg, which are in close agreement with our results of analysis of 15 different metals [37].…”

Present study was planned on the basis of prior field survey with main objective to determine concentrations of selected metals temporally (winter, spring, summer) in the industrial waste sediments, accumulate and enrich in the soils of Gujranwala city. Initially, physiochemical properties of samples pH (>8) colour (grey to black), odour (phenolic) and textures (amorphous to granular) were studied. Moisture contents 0.15-31% with RSD 0.17-16.87 shows variation because of seasonal effect. Overall, ICP-OES analysis reveals concentrations of thirteen selected metals in the range 0.40-379200 mg/kg with lowest of Ag and highest of Al. Statistically, RMANOVA was applied to reveal significant variations within the metals and between the seasons, showing significant metals effect seasonally. Environmental risk was estimated using geo-accumulation index and enrichment factor comparing reference crustal values (Bn) of metals in soil and Fe as reference metal. Aluminium accumulates very strongly and contaminate the soils more than Fe having no contamination in soil. Enrichment factor of Al also found highest indicating the highest enrichment level in the top soil. Overall, Fe and Al among thirteen elements found highest in quantity in the soil samples establishing significant impact in the soil due to their higher concentration. Finally, estimations are supporting the conclusion that metals may have a significant effect in soils where industrial waste is disposed.

“…Moreover, P. persica treatment with 10% CH 3 COOH resulted in the highest decrease of CPF, DFN, and CRB residues (86%, 97%, and 89%, respectively) than 10% NaCl and 10% NaOH. Amjad et al (2020) assessed the pyrethroid residues in 180 samples of okra and eggplant collected from the peri-urban agriculture of Gujranwala, Multan, and Faisalabad. Results revealed that 32% of the samples contained detectable residues of pyrethroid, while 6% of the samples had residues above maximum residual limit (MRL).…”
