Fluoride (F- ) exposure to air, soil, and water had the most detrimental impact on plants of all the halides. The element also had an adverse effect on a variety of physio-biochemical parameters after exceeding its desired limits in plants, with or without overt evidence of injury. Fluoride levels in plants are higher, which also inhibits plant growth by interfering with various pathways involved in photosynthesis, protein synthesis, respiration, nucleotide synthesis, and glucose metabolism. The two processes that plants use to get and use their basic energy are photosynthesis and respiration. Fluoride has a significant role in these two routes. This article explores the detrimental impacts on agricultural trees and crops ability to respire and produce oxygen and making food via photosynthesis.

“…Biochar surface area is linked to its capacity to adsorb small molecules such as gases and solvents. Furthermore, biochar can increase the availability of micronutrients including calcium (Ca), magnesium (Mg), boron (B) and molybdenum (Mo) by altering pH levels (Rondon et al, 2007;Major et al, 2010) and it can reduce the presence of certain plant growth inhibitors by adsorbing them (Sheldrake et al, 1978).…”

Intensive agricultural practices and poor management of organic waste have adverse effects on aquatic ecosystems, where excessive macroalgal proliferation can occur to form 'green tides', with negative environmental, ecological and socioeconomic impacts. One novel method for converting a problematic material into a valuable resource is to use excess algal biomass as a feedstock for biochar production. With a high elemental composition, such a resource might be suitable to redress soil deficiencies and to ameliorate soil fertility.Green macroalgae from the Ulva genus, in bladed (predominantly U. rigida), tubular (predominantly U. prolifera) and mixed morphological (U. rigida and U. prolifera) phenotypes, were used to produce biochars. A pot trial within a controlled-environment chamber was carried out to determine the effects of amending high-and low-fertilizer compost with algal biochars (applied at 0, 0.5, 1, 2 and 5% w/w) on the growth rate of Arabidopsis thaliana. A commercial woodbased biochar was used under similar treatments as a control. Weekly imaging and final harvest weights provided additional growth data; composition data including ultimate and proximate analyses, pH, Brunauer-Emmett-Teller (BET) surface area and hydropyrolysis of the dried macroalgae and algal biochars were also conducted.Significant enhanced growth in seedlings grown with biochar amendment were not observed in high-or low-fertilizer compost, and the addition of algal biochars at 5% w/w to high-fertilizer soil significantly reduced plant growth. Elemental analysis revealed that the algal biochars contained high quantities of alkaline elements including sodium. It was hypothesised that salinity was the primary factor affecting plant growth at higher biochar application rates, despite the algae being sourced from an estuarine environment. Biochar provenance and composition is highly significant: using the catch-all term 'biochar' ignores both the range of materials and composition that could be used to create it and its subsequent impact within the soil. HIGHLIGHTS• First plant trial using biochar predominantly from Ulva species.• Negative impact seen with 5% algal biochar on plant growth.• High sodium concentrations putatively identified as reduced plant growth cause.

Accumulation of Fluoride (F) was found in the soil and vegetation of the F-endemic villages of Gaya district, Bihar, India. The mean F level in the groundwater of F non-endemic (control) area was 0.59 ± 0.03 (n = 11), while that of F-endemic area was 2.36 ± 0.23 (n = 27). Water soluble F (WSF) and total F (TF) in the soil of F-endemic villages were significantly higher as compared to the F non-endemic area. Similarly, WSF and TF in the vegetables and the grain crops (cereals, legumes and oilseeds) of the F-endemic area were significantly higher as compared that of the control area. Leafy vegetables showed higher accumulation of F with WSF and TF in spinach ranging from 3.62 to 4.82 and 9.88-12.88 mg/kg respectively. The WSF and TF in coriander ranged from 9.66 to 10.88 and 23.11-25.73 mg/kg respectively.
