“…Mateos-Cárdenas et. al., [27], recently observed that at 24 and 48 h exposure of G. duebeni to PE MPs via trophic transfer from contaminated L. minor showed negligible effect on the amphipod mortality or mobility. Furthermore, juveniles of a planktivorous fish (Acanthochromis polyacanthus) showed great tolerance to acute and chronic exposure to polyethylene terephtalate (PET) with no significant effect on growth, body condition or behavior [74].…”

“…[79] also made similar observation for polystyrene (PS) on S. palustre L in freshwater. Overall, prolong exposure to the treatment showed increasing adherence to MPs in water by aquatic plant [27,79], thus they can be used for monitoring MPs contamination of freshwater environments.…”

“…Duckweed (lemma minor) and moss plant (Sphagnum palustre L). MPs made of polyethylene (PE) are adhering to whole L. minor colonies by exposing to 50,000 MPs/mL of size dimension of 10-45 μm [27]. Capozzi et.…”

“…lion, tiger, etc., may then be exposed through food-chain process or trophic transfer by consuming or feeding on herbivores tissues and bio-system. The food chain exposure processes are also often exhibited in the aquatic ecosystem, for example, whale or sharks feeding on smaller marine animals may have ingested MPs or amphipod Gammarus duebeni eating PE laden L. minor [27]. Generally, data on the presence of MPs in freshwater macroinvertebrates are scarce, as most studies have focused on fish and birds [34].…”

Plastic products with tremendous consumption are ubiquitous in our daily lives and the annual production of plastics is drastically increasing [1]. It is now expected to reach 33 billion tonnes by 2050 [2] with plastic waste in the environment projected to reach 67.8 million metric tons by the same year [3]. The pollution of plastic cum microplastics (MPs) from degradation in the environment is currently a hot issue attracting the global attention of many scientists, governmental and non-governmental organization and the public media [3-7]. Although few studies have investigated the chemical behavior and toxicity of MPs in the natural environment, studies focusing on its toxicity in tandem with toxic chemicals to ecosystems are scarce [1,4,8]. There are many toxicology reports that MPs are harmful to ecosystems. Terrestrial organisms such as earthworms, soil collembolans, and other animals, as well as plants have been affected by MPs [1,4,9-13]. Also, aquatic organisms such fish, sandhoppers, sea turtle, crustacean and mussel have also been affected by MPs [14-15]. In addition, humans are exposed to MPs via trophic transfer or by direct ingestion, contact and inhalation and plausible effects include lung inflammation and genotoxicity may occur [1,3,16,17]. Aside from the innate toxicity of MPs, they can carry different toxic chemicals such as heavy metals and organic pollutant by adsorption process, and double the effect of such pollutants [1,8,18]. Succinctly, plastic products are made up of mixtures of polymers, fillers, and multiple additives to improve its usability. Also, there are other chemicals including unreacted monomers, starting substances and non-intentionally added substances (NIAS; impurities, side or breakdown products) that are also present in plastic. However, most of these chemicals are not covalently bound to the polymer, so they can be released at all stages of the plastics' life cycle via migration to liquids or solids or via volatilization [1]. Therefore, plastic materials are an important source of human exposure to chemicals.

“…The leaves demonstrated 10% growth inhibition compared to less than 8% in control after a 7-day treatment, indicating an insignificant effect. Similarly, the increasing microbeads concentrations did not alter the levels of chlorophylls a and b significantly Contrarily, Mateos-Cárdenas et al revealed adding a concentration of 50,000 polyethylene microplastics/mL of water increased root length of duckweed (Lemma minor) between 24 hours and 168 hours after addition though the increase was insignificant compared to control the effects on root growth are inconclusive at this juncture, microplastics do not seem to significantly affect photosynthetic capacity of duckweed [24,25].…”

Effects of Microplastics on Agriculture: A Mini-review

Microplastics have permeated most, if not all, ecosystems including the terrestrial ones. The presence of microplastics in soil poses concerns on plants and agriculture. Microplastics alter soil biophysical properties including bulk density, water holding capacity and soil microbial interactions with water stable aggregates. The effects of microplastics on soil and plants frequently depend on the types and sizes of microplastics. This mini review presents a concise illustration of the impacts of microplastics on plants and crops. From the review, microplastics alter soil biophysical and chemical characteristics either positively or negatively depending on their types, concentrations, sizes and shapes. It reveals the ability of microplastics to affect enzymatic activities of plants which could lead to genotoxicity and oxidative damage. It unveils endocytosis of microplastics by specific plant cells as well as the uptake of microplastics via root and their accumulation and transport in plants facilitated by transpiration. This review also shows microplastics reduce root growth and seed germination at least transiently while do not seem to alter chlorophyll content. Microplastics were found to not interfere with phytoremediation of metals by the common reeds. This review highlights the need of more studies to confirm the effects of microplastics on crops and plants as the existing studies in this area are limited.
