Climate change has the potential to severely threaten the plant species in the forests of northeastern China. The field surveys performed for this study spanned 4 years and identified the endangered species present in the forests of northeastern China. We conducted a detailed investigation of 2,884 study plots and selected 29 nationally protected plant species (sample sizes ≥ 5), namely, threatened species for further analysis. We modelled and mapped the potential distributions of these 29 threatened species, and found that threatened species richness hotspots are currently distributed in the eastern and northeastern areas of the studied region and will move geographically. This study focused on the strategy for protecting threatened forest species richness by analysing the change trend of species richness and planning of priority protection areas due to climate change.

The mechanism and kinetics of toxic PCDDs destruction by OH radicals is investigated in detail by employing quantum chemistry. Results show that the OH radical degrades toxic PCDDs via substituting chlorine at the 2, 3, 7, 8 positions. The kinetic parameters are calculated by adopting transition state theory. The rate constant of OCDD destruction by OH is in agreement with the experimental result, especially at 298 K. The rate constants of 2, 3, 7, 8-TCDD destruction are obviously lower than those of other toxic PCDDs. The reason is discussed by using the NBO charge analysis. Owing to the activation effect of Cl atoms at 1, 4, 6, 9 positions, C atoms at 2, 3, 7, 8 positions have more negative charge. At aromatic rings, if the carbon has more negative charge, the carbon is more easily attacked by OH and the adjacent Cl is more easily substituted.

A new plume rise scheme for the Lagrangian stochastic model SPRAYWEB is developed and tested. The plume rise scheme is based on a stochastic differential equation for the potential temperature fluctuations coupled with the equations for the wind velocity fluctuation components. The new approach is tested against measured data from a water tank experiment (Weil et al., 2002). The results are discussed in terms of statistical indices and scatter plots. For the sake of comparison, the new scheme's performance is compared with the algorithm used in SPRAYWEB formerly proposed by Anfossi et al. (1993) which doesn't account for the temperature fluctuations. The results obtained with the novel plume rise scheme are generally satisfactory. A better agreement is found for the vertical standard deviation with respect to the results given by the Anfossi et al. (1993) scheme.

Results of air quality modelling are strongly influenced by the emission inventory used. This is related to spatial and temporal allocation of emission. In Poland, the share of residential combustion (RC) in total emission of particulate matter is large, and the temporal profile of emission from this sector is influenced by meteorological conditions. Here we show the performance of the WRF-Chem model forecasts, running for the area of Poland with two different approaches to temporal distribution of emission from RC. First, emissions are distributed temporally using the monthly, daily and hourly emission factors provided by GENEMIS project (base run). Second, the model uses the heating degree-day (HDD) approach RC. We show that both approaches result in similar model performance for PM10 and PM2.5. The HDD approach leads to better forecasts for the warm days, whereas the base run forecasts often show too high concentrations of atmospheric pollutants for such periods.

Currently, researches are mainly focused on how to recycle valuable metals from waste printed circuit boards (WPCBs), but rarely on the toxic substances, such as zinc and lead, during the recycling process. In this research, the effect of zinc and lead during the process of leaching copper from WPCBs by an acidic ionic liquid (IL), N-sulfobutylpyridinium hydrosulphate ([BSO4HPy]HSO4), was investigated in detail. Results showed that copper and zinc could be successfully leached out by [BSO4HPy]HSO4. When 1 g of 0.1 to 0.25 mm WPCBs powder was leached by 25 mL of 80% (v/v) ionic liquid and 10 mL of 30% hydrogen peroxide at 40°C for 2 h, copper and zinc leaching rate could be up to 99.75% and 93.02%, respectively. H2O2 added amount, solid-liquid ratio and temperature could significantly impact the leaching rate of copper and zinc. On the contrary, lead leaching rate is hardly influenced by these factors, maintaining at around 2%. Thus, during the leaching process, zinc could significantly influence the leaching of copper, which was totally different for lead. Leaching kinetics analysis indicated that the leaching of copper and zinc is controlled by solid film diffusion, and the leaching of lead is controlled by chemical reaction.

Increasingly the world over, climate modellers have suggested that local emissions may well affect cyclonic storms. The eastern coast of India, home to mega cities, is routinely battered by such storms over the period October to December. Additionally, these cities house millions of slum dwellers who cook their meals from unseasoned firewood yielding substantial amounts of biomass particles. These particles chemically age within a polluted air mass rendering them active as cloud condensation nuclei (CCN). This first study shows the genesis, progression and evolution of one such tropical disturbance, Hurricane Thane, which was modulated by these transient emissions, devastating the coast of Tamil Nadu on 30 December 2011. We show that auto-conversion rates converting cloud water to rain water are significantly altered by up to 12% with an increase of 20.5% in the cloud water amounts, when these effects are included
