1. Low level of mancozeb exposure affects ovary in mice
Jialu Bao, Yan Zhang, Ran Wen, Linchao Zhang, Xiaodan Wang Ecotoxicol Environ Saf. 2022 Jul 1;239:113670. doi: 10.1016/j.ecoenv.2022.113670. Epub 2022 May 24.
Mancozeb (MCZ) is widely used as a protective fungicide. This study aimed to explore the effects of low level MCZ exposure on ovary in mice. Twenty Kunming mice were randomly divided into control and MCZ groups (10 mice each). The mice in the MCZ group were given 100 mg/kg MCZ daily via gavage. The mice were sacrificed to collect serum and ovaries on day 31. The experimental indicators were then assessed. The weight of MCZ-exposed mice significantly reduced while ovarian index significantly increased compared with the control group. The FSH, LH, E2, P, CAT, SOD and MDA contents in the serum were significantly decreased and the content of estradiol significantly increased after MCZ exposure. Histological observation showed that the ovarian structure of mice exposed to MCZ was damaged, and the apoptosis was increased. Immunohistochemistry and RT-qPCR showed that the expression of Bax, caspase-3 and caspase-9 significantly increased in the MCZ- group. Conversely, Bcl-2 expression significantly decreased. Transcriptome sequencing showed that the expression of NADH dehydrogenase ND3, ND4L, ND6 subunits, Cyt b, and SDHC genes in mitochondria were down-regulated after MCZ exposure, similar to real-time PCR analysis. These results collectively indicate that the MCZ can affect the abnormal function of mitochondrial respiratory chain, lead to oxidative phosphorylation decoupling, produce oxidative stress, and finally cause ovarian injury and apoptosis in mice.
2. Effect of ozonated water, mancozeb, and thiophanate-methyl on the phyllosphere microbial diversity of strawberry

Phyllosphere microorganisms are closely linked to plant health. This study investigated the effect of ozonated water, mancozeb, and thiophanate-methyl on phyllosphere microorganisms in strawberry plants of the "Hongyan" variety. Sequencing analysis of the phyllosphere bacterial and fungal communities was performed using 16S rRNA gene fragment and ITS1 region high-throughput sequencing after spraying ozonated water, mancozeb, thiophanate-methyl, and clear water. Proteobacteria, Actinobacteria, and Firmicutes were the dominant bacterial phyla in strawberry. The relative abundance of Proteobacteria (82.71%) was higher in the ozonated water treatment group than in the other treatment groups, while the relative abundance of Actinobacteria (9.38%) was lower than in the other treatment groups. The strawberry phyllosphere fungal communities were mainly found in the phyla Basidiomycota and Ascomycota. The relative abundance of Basidiomycota was highest in the ozonated water treatment group (81.13%), followed by the mancozeb treatment group (76.01%), while the CK group only had an abundance of 43.38%. The relative abundance of Ascomycota was lowest in the ozonated water treatment group (17.98%), 23.12% in the mancozeb treatment group, 43.39% in the thiophanate-methyl treatment group, and 55.47% in the CK group. Pseudomonas, Halomonas, and Nesterenkonia were the dominant bacterial genera on strawberry surfaces, while Moesziomyces, Aspergillus, and Dirkmeia were the dominant fungal genera. Ozonated water was able to significantly increase the richness of bacteria and fungi and decrease fungal diversity. However, bacterial diversity was not significantly altered. Ozonated water effectively reduced the relative abundance of harmful fungi, such as Aspergillus, and Penicillium, and enriched beneficial bacteria, such as Pseudomonas and Actinomycetospora, more effectively than mancozeb and thiophanate-methyl. The results of the study show that ozonated water has potential as a biocide and may be able to replace traditional agents in the future to reduce environmental pollution.
3. Interaction of mancozeb with human hemoglobin: Spectroscopic, molecular docking and molecular dynamic simulation studies
Ruhul Quds, Md Amiruddin Hashmi, Zarmin Iqbal, Riaz Mahmood Spectrochim Acta A Mol Biomol Spectrosc. 2022 Nov 5;280:121503. doi: 10.1016/j.saa.2022.121503. Epub 2022 Jun 15.
Mancozeb is a broad-spectrum fungicide used extensively in agriculture to protect plants from numerous diseases. Hemolysis of human erythrocytes on exposure to mancozeb has been reported. In the present study, we investigated the interaction of mancozeb with human hemoglobin (Hb) using multi-spectroscopic techniques, molecular docking and molecular dynamic simulation. UV-visible spectroscopy studies suggested intimate binding of mancozeb to Hb. Mancozeb quenched the intrinsic fluorescence of Hb and Stern-Volmer plots revealed that the quenching mechanism was of static type. Evaluation of thermodynamic parameters indicated that the binding of Hb to mancozeb was spontaneous, with van der Waals forces and hydrogen bonding being the key contributors in the binding reaction. Synchronous fluorescence experiments demonstrated that mancozeb altered the microenvironment around tryptophan residues, whereas polarity around tyrosine residues was not changed. Circular dichroism studies showed a decrease in the α helical content of Hb upon interaction with mancozeb. The inhibition of esterase activity showed that mancozeb can impair the enzymatic functions of Hb. Molecular docking study revealed that strong binding affinity existed between mancozeb and Hb, with hydrophobic forces playing a crucial role in the interaction. Molecular dynamic simulation showed that mancozeb formed a stable complex with Hb resulting in slight unfolding of the protein. To sum up, the results of this study show that mancozeb binds strongly to Hb, induces conformational changes in Hb and adversely affects its function.
