petrol
Leaded petrol, paints and diffuse urban uses are considered as sources of these anomalies.
      
The continuing production of leaded petrol generates liquid wastes containing recalcitrant trialkyl lead, for which no suitable chemical treatment has been formulated.
      
The blend was fractionated into petrol-ether-insoluble poly(3HB) and petrol-ether-soluble poly(3HHx-co-3HO).
      
Observed Pb enrichments and low 208Pb/204Pb, 207Pb/204Pb and 206Pb/204Pb ratios are likely caused by atmospheric deposition of Pb additives from petrol and subsequent Pb transport by road run-off waters into the local drainage system.
      
The Pb isotopic compositions of the stream sediments overlap the values of Pb in petrol.
      
There are also point sources of pollution, such as wastewater, landfills, golf courses, industrial zones, quarries and petrol stations.
      
The simulations predict the order-disorder transition in omphacite at 1,150?±?20°C in good agreement with the experimental data of Carpenter (Mineral Petrol 78:433-440, 1981).
      
End-of-life vehicle recycling starts with the removal of dangerous materials, such as oil, fuel and LPG-tanks (Liquefied Petrol Gas).
      
The application of the laser diffraction and the phase Doppler techniques to small diameter dense sprays, such as those produced by Diesel and petrol injectors leads to differences between the measured sizes.
      
For example, the Sauter mean diameter measured by laser diffraction was 30% smaller than the line-of-sight estimates from the phase Doppler measurements in the petrol spray and 100% smaller in the Diesel spray.
      
In this paper we report the results of a small scale experiment (a 3?m long flume) to measure long waves of small to large amplitude at the interface of two non-miscible fluids (water and petrol).
      
Weiterhin wurde zur Vermeidung einer m?glichen thermischen Zersetzung des Queck0silberalkyls dieses in Petrol?ther gel?st in den Versuchsraum gesprüht.
      
The detergent scrub technique was used for harvesting corneocytes from three body regions (forehead, palm, and sole) of normal persons (n=20) under casual conditions and after thorough defattening of the skin with 70% isopropyl alcohol or petrol.
      
A discussion of Hunter and Sparks (Contrib Mineral Petrol 95:451-461)

At X(H2O)=1.0, the equilibrium lies between 2.25 and 2.30?GPa, in good agreement with the 2.30-2.45?GPa reversal of Holland (Contrib Miner Petrol 68:293-301, 1979).
      
These values approach X(H2O)2, and agree well with the a(H2O) model of Aranovich and Newton (Contrib Miner Petrol 125:200-212, 1996).
      
(Contrib Mineral Petrol 142:15-26, 2001) studied the diffusion of Si, Mg and O in synthetic polycrystalline enstatite reaction rims.
      
(Contrib Mineral Petrol 142:15-26, 2001) used the formalism of LeClaire (J Appl Phys 14:351-356, 1963) to derive the coefficient of silicon grain boundary diffusion from stable isotope profiles across the reaction rims.
      
However, recent melting experiments (Sisson et al., Contrib Mineral Petrol 148:635-661, 2005) demonstrate that extreme fractional crystallization or partial melting of K-rich basalts can produce these silicic magmas.
