Interactions of Microplastics with Pesticides in Soils and Their Ecotoxicological Implications

| Sumario: | Highlights: Soil pollution by microplastics (MPs) has steadily grown in recent years. MPs may interact with pesticides that reach the soil during pest control. MPs increase adsorption and reduce transport and degradation of pesticides. No major effects of soil properties on MP–pesticide interactions. Joint MPs–pesticides exhibit variable toxic effects on soil organisms. In the middle of the 20th century, the production of plastics exploded worldwide because of their low cost and the versatility of their applications. However, since plastic debris is highly resistant to environmental degradation, a growing presence of plastics in all the ecosystems has been confirmed. Among them, plastic particles < 5 mm, also known as microplastics (MPs), are of special concern because they are dispersed in aerial, terrestrial and aquatic environments, being the soil the main environmental sink of these contaminants. Due to their large specific surface area and hydrophobicity, MPs are considered good adsorbents for other environmental organic pollutants also present in terrestrial ecosystems, such as pharmaceuticals, personal-care products or pesticides with which they can interact and thus modify their environmental fate. In this review article, we examine the recent literature (from 2017 to 2022) to get a better understanding of the environmental fate of pesticides in soil (adsorption, mobility and/or degradation) when they are simultaneously present with MPs and the ecological risks on living organisms of the interactions between MPs and pesticides in soil. More studies are needed to fully understand the toxicological impact of the copresence in soil of pesticides and MPs. |
