Hyphenation
Exercise C-4. Improper hyphenation (with minor editorial changes).
Here are ten sentences from the scientific literature that contain erroneous hyphenation. Find each error, state why it is wrong, and fix it. Rewrite the sentences more generally as you feel led.
1. To this end, injecting a nontoxic stimulatory substrate downgradient of a BTX plume might be a cost effective approach to enhance the growth and viability of BTX degraders before the arrival of the plume.
2. A qualitative assessment of microbial population shifts was conducted by spread plating dilutions of aquifer material collected from the inlet of aquifer columns at the end of the first experiment.
3. For pesticides, both covalent bonding and sorption appear to reduce pesticide residue bioavailability.
4. The crude cell extract suspension containing the polar product was cooled in an ice bath to 0 ºC.
5. An alternate method for apportioning black carbon concentrations between light-duty vehicles and heavy-duty diesel trucks was considered.
6. Driving conditions inside the tunnel were determined using an instrumented vehicle equipped to log speed at 1 s intervals.
7. In contrast, gasoline engine derived PAH emissions were found almost entirely in the ultrafine mode.
8. Measurements of vehicle exhaust in prior roadway tunnel experiments show that PAH with molecular weights ³228 (e.g., benz(a)anthracene, chrysene, and larger PAH) are entirely in the particle phase.
9. It can be concluded that no significant modification of the natural trace element speciation occurred.
10. Experiments on horizontal but down-facing samples at heights of 2 and 6 m indicated a flux at least an order of magnitude lower than on vertical samples.
