“…In the framework of this paper, the earlier database (Agathokleous et al 2020b) was extended by adding 121 dose responses of chlorophylls to The rise and fall of photosynthesis: hormetic dose response in plants 1 3 22 stresses, mined from 25 published studies (of which 67% were published in 2020) with 24 species of higher plants, including tree and other perennial plants (Table S1). The 22 stresses included herbicides (Liu et al 2019;Meseldžija et al 2020), human and veterinary antibiotics (Guo et al 2020;Liu et al 2020a), metallic elements (Seth et al 2008;Tang et al 2009;Jia et al 2015;Apodaca et al 2017;Wu et al 2018;Li et al 2020a;Małkowski et al 2020;Mo et al 2020;Yang et al 2020), micro/nano-plastics (Dong et al 2020;Li et al 2020c;Lian et al 2020;Pignattelli et al 2020), and various other types (Mostofa et al 2015;Wang et al 2016;Soliman et al 2019;Kutty et al 2020;He et al 2020;Gohari et al 2020b, a;Trejo-Téllez et al 2020). More than half (57.0%) of the new dose responses were statistically significant compared with the control group (typically a zero dose of the same stressor), according to the original analysis (many of them did not report statistics).…”

“…These data were collected and further analyzed; 45.5% of the mined dose responses with higher plants and 44.4% of the mined dose responses with algae and duckweeds were statistically significant according to the original analyses of authors (Supplementary Information, Tables S3−S4). The median MAX was 133.0% for higher plants (geometric mean = 140.8%) and 138.1% for algae and duckweeds (geometric mean = 145.2%) exposed to human and veterinary antibiotics (Liu et al 2020a), herbicides (Rioboo et al 2002;Liu et al 2019; Zaltauskaite and Kaciene 2020), metallic elements (Jia et al 2015;Zhou et al 2018;Wu et al 2018;Hussain et al 2019;Liu et al 2019), micro/nano-plastics (Li et al, 2020c, d;Pignattelli et al 2020;Song et al 2020), and other stressinducing agents (Mostofa et al 2015;Farzana and Tam 2018;Dawood and Azooz 2019;Lassalle et al 2019;Li et al 2019;Soliman et al 2019;Tombuloglu et al 2019;Gohari et al 2020b, a). The median MAX did not differ significantly between the two groups of organisms, although the sample size was small (Fig.…”

The recent recognition that low doses of herbicides, human and veterinary antibiotics, metallic elements, micro/nano-plastics, and various other types of environmental pollutants widely enhance chlorophylls in the framework of hormesis created the need to further evaluate the response of photosynthetic pigments and gas exchange to low doses of stresses. An analysis of about 370 values of maximum stimulatory response (MAX; percentage of control response, %) of chlorophylls in higher plants, algae and duckweeds, and other photosynthesizing organisms, mined from published literatures, revealed a greater MAX for higher plants (median = 139.2%) compared to algae and duckweeds (median = 119.6%). However, an analysis of about 50 mined values of MAX of carotenoids revealed no significant difference in the median MAX between higher plants (median = 133.0%) and algae-duckweeds (median = 138.1%). About 70 mined values of MAX were also concentrated for photosynthetic rate (median MAX = 129.2%) and stomatal conductance (median MAX = 124.7%) in higher plants. Within higher plants, there was no significant difference in the median MAX among chlorophylls, carotenoids, photosynthetic rate, and stomatal conductance. Similarly, there was no significant difference in the median MAX between chlorophylls and carotenoids of pooled algae and duckweeds. The results suggest that the MAX is typically below 160% and as a rule below 200% of control response, and does not differ among chlorophylls, carotenoids, photosynthetic rate, and stomatal conductance. New research programs with improved experimental designs, in terms of number and spacing of doses within the “low-dose zone” of the hormetic dose–response relationship, are needed to study the molecular/genetic mechanisms underpinning the low-dose stimulation of photosynthesis and its ecological implications.

“…15,16 Moreover, where the toxicity of the plastic is studied empirically, there is oen a distinct lack of material characterisation and identication or quantication of the additives present. [17][18][19][20][21] To this end, we present a compilation of data derived in our laboratory from X-ray uorescence analyses on the relative abundance of PVC in both consumer plastics and plastics lost to the environment (environmental plastics). Specically, we report and compare the degree of chlorination and concentrations of metals (including the metalloid antimony, Sb) used in stabilising additives and halogenated ame retardant synergists in consumer and environmental samples of PVC.…”

“…Besides, PVC MPs of sizes less than 0.5 mm had an acute and chronic toxicity on the growth of garden cress (Lepidium sativum) [82,83]. Furthermore, Hernández-Arenas et al [84] studied the effect of sewage sludge containing MPs on the development of tomato plants in term of biomass and lenth for shoot and root, and the stem diameter and tomato production.…”

Microplastics (MPs) are pertinacious contaminants which are threatening the delicate balance of the ecosystem. Over the years, various studies have reported the presence of MPs in the marine environment through case studies and reviews, but its presence in the agricultural soils is not fully understood. To date, there exists no standardized methodology for sampling, extraction and characterization of MPs in the agricultural soils. This review aims at encapsulating the different techniques used for sampling and extraction of MPs, and includes the methods employed for identification and quantification of MPs in the soil environment. Flotation method, pressurized fluid extraction and elutriation are some of the different techniques used for MPs extraction that usually influence the characterization step. Visual identification through microscope and scanning electron microscope and chemical identification via Fourier-transform infrared (FITR) and Raman spectrometry, are the main techniques that are used for the identification of MPs. The fate and dispersion of MPs in the agricultural soil are discussed, as well as their interaction with the soil biota. The main findings of this review show that further research is needed on the sampling methods as well as analytical techniques so as to contribute to standardizing MPs characterization in the soil environment, potential toxicity effects along the food chain, and global policies for sustainable development.
