“…Wendt-Rasch et al (2003) reported no significant effects on copepod nauplii www.intechopen.com and rotifers from exposure during 14 days to metsulfuron methyl (0, 1, 5, 20 g/L) in 24 enclosures of 80 L (height: 0.65 m, diameter: 0.4 m) in water bodies adjacent to agricultural fields. Metsulfuron methyl is a sulfonylurea herbicide that affects the synthesis of essential amino acids in plants, and hence inhibits cell division.…”

“…Secondary effects of herbicides on these organisms are difficult to predict since they depend on interactions between species, herbicides and the original structure of the ecosystem (Wendt-Rasch et al, 2003). For aquatic ecosystems, toxicity testing ranges from standard tests under laboratory conditions to field studies, including microcosm and mesocosm experiments (Caquet et al, 2000).…”

“…For aquatic ecosystems, toxicity testing ranges from standard tests under laboratory conditions to field studies, including microcosm and mesocosm experiments (Caquet et al, 2000). These studies in enclosures are valuable tools that can help to understand how herbicides exposure may affect ecosystems as a whole, and be an aid in the assessment of the various risk scenarios resulting from the use of these chemicals (Wendt-Rasch et al, 2003).…”

Abiotic Stress Responses in Plants

Several environmental factors infl uence the mineral uptake of plants, including pH, redox potential, and the presence of xenobiotics as well as the temperature and salinity. Changes in environmental conditions affect the biological and physiological response of plants. Most important targets of plants are maintained by the ion homeostasis and mineral uptake in stress conditions. Plants may use the different procedures to regulate homeostasis. In general, Na salt stress decreases the levels of cationic nutrients such as K, Ca, and Mg due to competition for ion transport sites. Drought and salinity stress are physiologically related and the tolerance mechanisms overlap. Metals can interfere with mineral nutrition and change the concentration and composition of plant nutrients. Besides, metals may also alter the conformation of proteins, including transporters, or regulator proteins. Herbicides may disrupt the function and integrity of the cell membrane, and signifi cant ion losses can occur. However, molecular mechanisms and genetic basis of interactions between abiotic stress and mineral uptake is lacking. Thus, future studies will focus on these aspects. In this chapter, the effects of some common stressors, such as salinity, drought, metals, herbicides, and on nutrient uptake are elucidated.

Toxicokinetic and toxicodynamic models are a promising tool to address the effects of time-variable chemical exposure. Standard toxicity tests usually rely on static concentrations, but these chemical exposure patterns are unlikely to appear in the field, where time-variable exposure of chemicals is typical. In the present study, toxicodynamic processes were integrated into an existing model that includes the toxicokinetics and growth of the aquatic plant Myriophyllum spicatum, to predict the impact on plant growth of 2 iofensulfuron short-term exposure patterns. To establish a method that can be used with standard data from risk assessments, the toxicodynamics of iofensulfuron were based on effect data from a 14-d standard toxicity test using static concentrations. Modeling showed that the toxicokinetic and toxicodynamic growth model of M. spicatum can be successfully used to predict effects of short-term iofensulfuron exposure by using effect data from a standard toxicity test. A general approach is presented, in which time-variable chemical exposures can be evaluated more realistically without conducting additional toxicity studies.
