“…In the northern KwaZulu-Natal, a province of South Africa where DDT has been used for more than 80 years for malaria control, aquatic bird eggs including Pelican eggs, Little Egret eggs, African Openbill eggs and White-breasted Cormorant eggs were still showed DDT residues (Bouwman et al, 2019). In addition, higher concentrations of DDT (969.52 pg/g) were observed than the other pesticides in soil samples from Amghara, Kuwai (Alshemmari, 2023). Thus, wildlife, especially avian embryos in fertilized eggs, is still at risk of DDT.…”

In ovo exposure to o,p′‐dichloro‐diphenyl‐trichloroethane (o,p′‐DDT) impairs reproduction by inducing malformation of the reproductive organs in birds, although the mechanism remains unclear. Here, we examined the effects of o,p′‐DDT on the development of the reproductive organs, the expression of genes controlling sexual differentiation, and the plasma concentrations of testosterone and estradiol in Japanese quail embryos. o,p′‐DDT‐containing sesame oil was injected into the yolk sac on Embryonic Day (E) 3 at a dose of 500, 2,000, or 8,000 μg per egg. On E15, the reproductive organs were observed; the gonads and Müllerian ducts (MDs) were sampled to measure the mRNA of steroidogenic enzymes, sex steroid receptors, anti‐Müllerian hormone (AMH), and AMH receptor 2 (AMHR2); blood samples were collected to assay plasma testosterone and estradiol levels; and the gonads were used for histological analysis. o,p′‐DDT dose‐dependently increased the prevalence of hypertrophic MDs in females and residual MDs in males. In female MDs, o,p′‐DDT dose‐dependently decreased estrogen receptor (ER) α, ERβ, and AMHR2 mRNA expression. o,p′‐DDT dose‐dependently induced left‐biased asymmetry of testis size, and ovary‐like tissue was found in the left testis after exposure to 8,000 μg per egg o,p′‐DDT, although asymmetric gene expression did not occur. o,p′‐DDT did not affect ovarian tissue but did decrease 17α‐hydroxylase/C17‐20 lyase mRNA expression and dose‐dependently increased ERβ mRNA expression. o,p′‐DDT decreased plasma testosterone concentrations in females. These findings suggest that o,p′‐DDT induces hypertrophy of the MDs and ovarian tissue formation in the left testis. Abnormal MD development may be linked to altered gene expression for sensing estrogens and AMH signals.

Being a famous hometown of vegetables in China, Shouguang City has a long history of vegetable cultivation and is a comprehensive national commodity base for vegetables and fruits. In recent decades, with the expansion of agricultural production, the use of pesticides is increasing. Although organochlorine pesticides (OCPs) have been banned, there are still some residues in soil, groundwater and other media. The study on the migration of the OCPs in soil and groundwater is of great importance for the maintenance of food security. Using methods of hydrogeological survey, laboratory testing and numerical simulation, the spatial distribution characteristics, sources and pollution degree of OCPs in soil and groundwater were analyzed, and the migration and transformation of OCPs in soil–groundwater was dynamically simulated and predicted. The study showed that there were many kinds of OCPs residual in the soil environment. The hexachlorocyclohexane (HCHs) in the topsoil of the study area were mainly due to the use of lindane, and the main source of dichlorodiphenyltrichloroethane (DDTs) in soil was the use of DDTs in history. The contents of HCHs, DDTs and hexachlorobenzene in the topsoil of the study area were at a low level, while the content of endosulfan metabolite endosulfan sulfate was comparatively higher. In recent years, the content of organochlorine pesticides in soil has generally decreased. The indexes of OCPs in groundwater can meet the Standards for Drinking Water quality of China. It was predicted that the HCH pollutants would mainly be distributed in Gucheng Street, Shangkou Town, and its south area where the concentration exceeds 3 ng/L exceeds that of 240 km2. DDT pollutants would mainly be distributed in the east and north of Shouguang City, where the concentration beyond 0.6 ng/L exceeds that of 200 km2. Endosulfan sulfate pollutants would mainly be distributed in the Gucheng Street Office, Shangkou Town, and its south area where the concentration exceeds 1.5 ng/L will exceed that of 150 km2. Hexachlorobenzene (HCB) pollutants would mainly be distributed in Fengcheng in the west of Shouguang City and Nancha River in the northeast, where the concentration exceeds 0.2 ng/L will exceed that of 200 km2. The study enriched the monitoring data of OCPs in agricultural planting areas and provided reference for source analysis, migration prediction, and pollution prevention of OCPs.
