“…The use of pesticides and fertilizers in these forms might also have contributed to the soil and air Pb content. Soil Pb content in samples from Al-Wafra was reported to be higher than the normal acceptable limits (38).…”

Background: Environmental lead (Pb) exposure is a public health problem in many developing and industrialized countries. Being a petrochemical industry-based economy, Pb levels are expected to be high in Kuwait but systematic data on population exposure are lacking. This study aimed at determining the prevalence of Pb toxicity in adolescents in Kuwait.Methods: Adolescents (N=1385; age range 11-16 years) were cross-sectionally selected from public middle schools from all Governorates of Kuwait, utilizing multi-stage cluster random sampling. Pb in whole blood was analyzed by inductively coupled plasma mass spectrometry. Pb levels among Governorates and genders were compared by median test and the prevalence of Pb levels above the CDC cutoff (≥5 µg/dL) was estimated by x2 test. Multiple logistic regression was used for association between prevalence of high Pb levels and Governorate.Results: Median (IQR) Pb was 5.1(3.6 – 7.1) µg/dL [4.9 (3.8 6.5) µg/dL in males and 5.4 (3.3-7.6) µg/dL in females; p=0.001]. In the overall sample, 51% had Pb levels ≥5 µg/dL; 13% were ≥10 µg/dL and 3% >20 µg/dL. Prevalence of Pb ≥5 µg/dL was 47% in males and 56% in females (p<0.001). High Pb levels were clustered in Al-Asima and Al-Ahmadi (in both genders); Al-Jahra (in males) and Mubarak Al-Kabeer (in females) Governorates.Conclusion: Pb exposure is a significant public health problem in adolescents in Kuwait. Urgent public health intervention is required in high Pb exposure areas and further research is needed to identify the sources of exposure in these areas for prevention.

“…In addition, this Governorate has an agricultural site (Al-Wafra), where the use of pesticides and fertilizers could contribute to the soil and air Pb content. Soil and air samples from these two Governorates have been reported to contain higher levels of Pb [ 13 , 15 , 43 , 44 ]. The Governorate of Mubarak Al-Kabeer is located next to the Al-Ahmadi Governorate and the spill-over of the environmental Pb is suspected to be the reason for EBLLs.…”

Background Elevated blood lead level (EBLL) is a public health problem in both developing and industrialized countries. Being a petrochemical-based economy, lead (Pb) levels are expected to be high in Kuwait, but systematic data on population exposure are lacking. This study aimed at determining the prevalence of EBLL in adolescents in Kuwait. Methods Adolescents (N = 1385; age range 11–16 years) were cross-sectionally selected from public middle schools from all Governorates of Kuwait, utilizing multistage cluster random sampling. Pb in whole blood was analyzed by inductively coupled plasma mass spectrometry. Distribution of blood Pb levels (BLL) among Governorates and sexes were compared by non-parametric tests and the prevalence of EBLL (defined as BLL above the CDC reference level of ≥5 μg/dL) was estimated by χ2 test. Binary logistic regression was used for assessing the association between EBLL and Governorate. Results Median (IQR) BLL was 5.1(3.6–7.1) μg/dL [4.9 (3.8–6.5) μg/dL in males and 5.4 (3.3–7.6) μg/dL in females; p = 0.001]. In the overall sample, 51% had BLL ≥5 μg/dL; 13% had ≥10 μg/dL and 3% > 20 μg/dL. Prevalence of EBLL was 47% in males and 56% in females (p < 0.001). EBLLs were clustered in Al-Asima, Al-Ahmadi (in both sexes); Al-Jahra (in males) and Mubarak Al-Kabeer (in females) Governorates. Conclusions EBLL is a significant public health problem in adolescents in Kuwait. Urgent public health intervention is required in areas with EBLL, and the sources of exposure need to be identified for prevention.

“…One form of bioremediation is rhizoremediation, which is a process where microorganisms degrade contaminated soil in the root areas. This process uses plant roots and a consortium of microbes to degrade environmental pollutants and restore the contaminated soil area to a condition that can be used for the intended purpose [8]. According to [9], all plants can absorb metals in varying amounts, but some plants can accumulate certain metal elements in high enough concentrations.…”

Heavy metal pollution from anthropogenic sources is a serious problem for the environment, one of these Pb. Besides industrial waste, the use of chemical fertilizers and pesticides in the agriculture sector can increase heavy metal concentration in the soil. One impact of climate change is the change of rainfall patterns. Some areas suddenly experienced a long drought, forcing farmers to irrigate their fields using industrial wastewater which contains hazardous compounds such as Pb. Bioremediation technology using the plant in combination with microorganisms and organic matter as the bioremediation agent is one way to restore polluted soil as an effort to improve the environment carried out in this study. The purpose of this study was to study the effect of inorganic fertilizers and bioremediation agents on efforts to reduce soil Pb levels with Biduri and the ability of Biduri as Pb hyperaccumulator plants. This study used a factorial experimental design with a completely randomized design with three factors and three replicates. The use of Biduri with a combination of inorganic fertilizers, bioremediation agent, and doses of Pb is able to reduce Pb levels in the soil so that it can be used as an alternative to reduce soil pollution, one of the consequences of climate change which has an impact on agriculture and Biduri in this study have potential as hyperaccumulator plants for Pb.
