“…However, the objective of the diversification strategies is not to eliminate all the weeds, instead to control them. Weeds offer various ecosystem services, which sometimes are beneficial to crops and humans [42][43][44][45][46][47].…”

Weeds are among the major constraints to any crop production system, reducing productivity and profitability. Herbicides are among the most effective methods to control weeds, and reliance on herbicides for weed control has increased significantly with the advent of herbicide-resistant crops. Unfortunately, over-reliance on herbicides leads to environmental-health issues and herbicide-resistant weeds, causing human health and ecological concerns. Crop diversification can help manage weeds sustainably in major crop production systems. It acts as an organizing principle under which technological innovations and ecological insights can be combined to manage weeds sustainably. Diversified cropping can be defined as the conscious inclusion of functional biodiversity at temporal and/or spatial levels to improve the productivity and stability of ecosystem services. Crop diversification helps to reduce weed density by negatively impacting weed seed germination and weed growth. Additionally, diversified farming systems are more resilient to climate change than monoculture systems and provide better crop yield. However, there are a few challenges to adopting a diversified cropping system, ranging from technology innovations, government policies, farm-level decisions, climate change, and market conditions. In this review, we discuss how crop diversification supports sustainable weed management, the challenges associated with it, and the future of weed management with respect to the diversification concept.

“…Although Plantago have been mostly used for assessing heavy metal contamination via accumulation studies (Nadgórska-Socha et al 2017 ; Amato-Lourenco et al 2020 ), this taxon is also applicable for assessing airborne PAH pollution. In a comparative study, greater plantain ( Plantago major L.) accumulated higher concentrations of PAHs than grass species, most probably due to leaf characteristics (Bakker et al 2000 ).…”

Biomonitors are considered a cheap alternative of active air samplers, especially where spatial pattern of air quality is to be monitored, requiring numerous parallel measurements. Of higher plants, Plantago lanceolata L. has been proven a good monitor species with proper accumulation capacity. While biomonitoring studies are difficult to compare due to inherent errors such as the diverse plant material used in different studies, the No. 227 OECD GUIDELINE FOR THE TESTING OF CHEMICALS: Terrestrial Plant Test: Vegetative Vigour Test provides a tool to test extract of aerosol samples under controlled laboratory conditions. In our study, this guideline was followed to experimentally treat Plantago with the aqueous extract of a diesel exhaust sample. Accumulation pattern of polyaromatic hydrocarbons (PAHs) was assessed and compared to samples collected in the field. Unlike most studies reported in the literature, both in the experimentally treated and field Plantago samples, high ratio of high molecular weight PAHs was experienced. Distribution pattern of accumulated PAHs showed strong correlation between the experimentally treated sample and most of the field plantain samples, underlying the usefulness of laboratory treatments for bioaccumulation studies.

“…Nonetheless, the content of various pollutants in fruits from trees grown near urban and/or industrial areas might exceed safety limits [11,19,23,36]. The most important source of pollution for fruits seems to be airborne PM, emitted e.g., from road sources [12,29,38,39]. In the present study, apples and plums fruits accumulated considerable amounts of PM.…”

“…In the present study, three roads with varying levels of traffic (Tables 1 and 4) were expected to be the main source of PM in examined orchards. It has previously been shown that road transport sources, both exhaust and non-exhaust, account for significant PM emissions [11,28,[30][31][32]43] and may be the reason for pollution accumulation in edible plants [29,38,39]. Road PM emission is increased by the number and size of vehicles [32,[44][45][46], average speeds and sudden changes in speed [44,46,47], and is higher in spring and summer than in winter, and higher during the week than at weekends [28].…”

Particulate Matter Accumulation on Apples and Plums: Roads Do Not Represent the Greatest Threat

et al. 2020

Particulate matter (PM) is a mixture of solid and liquid substances of organic and inorganic character suspended in air. Plants are used as biological filters of air. However, PM can be deposited on their edible parts, with a negative effect on people’s health. The aim of this study was to document the PM accumulation on apples and plums harvested from orchards located alongside roads with differing amounts of traffic. Plums accumulated more PM than apples. The deposition of PM on apples increased during fruit development and was highest at harvest. The impact of road type, traffic intensity, and distance from the road on PM accumulation on fruit was small. The least PM was adsorbed by apples harvested from an orchard located close to a road with the highest traffic, while in the case of plums, no effect of the road on PM deposition was recorded. The amount of PM accumulated on fruits depended on the species (fruit morphology, harvest period), activities undertaken in the orchard (early pruning exposes fruits to PM, ecological preparations increase fruit viscosity), and sources of pollution other than the roads located close to the orchard. Washing fruits with water removed half of the accumulated PM.
